ELECTRICITY AND MAGNETISM BASICS - This module will introduce you to many of the basic concepts involved with Electricity and Magnetism. It is suggested that you review the MATTER module in the Chemistry section first. We will introduce you to static charge, moving charge, voltage, resistance, and current. You will be able to discover Ohm's law. We will learn about the properties of magnets and how magnets are used to produce electric current. Exactly what is electricity? Click HERE.
Any object or particle is or can become electrically charged. No one completely understands what this charge consists of but we do know a lot about how it reacts and behaves. The smallest known charge of electricity is the charge associated with an electron. This charge has been called a "negative" charge. An atoms nucleus has a positive charge. These two un-like charges attract one another. Like charges oppose one another. If you had 6,250,000,000,000,000,000 electrons in a box you would have what has been named; one coulomb of charge. An easier way of thinking about a large number like that is called "powers of ten" and it would look like this 6.25 x 1018 electrons. It is simply a way to let you know to move the decimal point to the right 18 places. When electrical charges are at rest, meaning they are not moving, we call that static electricity. If charges are in motion we then have a flow of charge called electrical current. We have given the force that causes this current a name called electromotive force and it is measured by a unit called a volt. The unit of measurement of the current or movement of the charge is called an ampere. The resistance, or opposition, to current flow is called an ohm.
Around a charge is an electric field. With every electric field there is a magnetic field. While we can't see these fields, or yet know exactly what they consist of, we can measure them with instruments and tell a great deal about their behavior. We can then use this knowledge to our benefit. The design and construction of electric motors, computers, radios, televisions, stereos, and many other electrical and electronic devices depend upon a knowledge of these basic principles of electricity. As you can see we have given names to these phenomenon to make it easier for us to study and use. We could have called them Dick, Jane and Mary but instead we named them for the scientists that discovered or first studied them; Volt, Ampere, and Ohm. Mr. Volt, Mr. Ampere, and Mr. Ohm spent many years of their lives studying electricity. They were not alone however as many other scientist were studying and learning more about electricity as well.

RESISTANCE - is the opposition to current flow. The practical unit of resistance is called the ohm. A resistance that develops 0.24 calorie of heat when one ampere of current flows through it for one second has one ohm of resistance.
OHMS
LAW -
Learning basic electronics starts with learning Ohm's law and
A GREAT Ohms Law CALCULATOR online - http://www.cvs1.uklinux.net/cgi-bin/calculators/ohms_law.cgi
Ohms Law Calculator with Watts: http://www.anderson-bolds.com/calculator.htm
To learn about Ohm's law click >>HERE. I = V/R, V = I*R, R = V/I, and P = I*V are the fundamental formulas of Ohm's law. (The * means to multiply the two quantities together). Where V is the circuit voltage in volts, I is the circuits amperage in amps, and R is the resistance in ohms. As an experiment you can set up a circuit by connecting resistors in series with a battery, measure the voltage across the resistors with a voltmeter, measure the current in the circuit by placing an ammeter in series with the resistors and battery. If you know the voltages and current in the circuit you can use Ohms law to calculate the resistance. With the resistor out of the circuit you can measure it's resistance directly with an ohm meter. The multi-meters today can measure ohms, volts and amperes (usually miliamperes) all in one piece of test equipment.

Confused? Take a look at the resistor
circuits next and that should help. Then come back to ohms law and it
should make more sense.

For
a definition of a resistor see this link http://searchsmb.techtarget.com/sDefinition/0,,sid44_gci213522,00.html
Resistors can be connected in series (end to end), in parallel (across one
another), or in a combination of series and parallel. To learn
more about resistor circuits click
- here.
If you connect two, 1/4 watt, 100 ohm resistors across one another (i.e. in
parallel) then the total resistance in ohms is one half of one of the
resistors. In this example the resistance would be 50 ohms. The
wattage doubles as the current is now split between the two resistors.
The combination can now handle up to one half a watt safely. If the two
resistors were connected end-to-end (i.e. in series) the resistances add and
in this case would be 200 ohms. The wattage in this series case stays
the same, 1/4 watt. This information is handy to know as it is easy to
calculate in your head and will allow you to devise additional resister values
from a limited resistor bench stock.
RESISTORS IN SERIES: Connecting resistors in a string one pigtail to another is called connecting them in series. When connected this way the resistance of one resistor adds to the next in line. For example a 100 ohm resistor in series with a 500 ohm resistor is the same as having a 600 ohm resistor. The wattage capability stays the same, in other words if the resistors are all 1/4 watt the string is 1/4 watt.
Resistance in series resistance simply adds: R = R1 + R2. This can be extended for more resistors: R = R1 + R2 + R3 + R4 + ...
RESISTORS IN PARALLEL: When resistors are connected in parallel (parallel; meaning they are tied across one another) their combined resistance is less than any of the individual resistances. There is a special equation for the combined resistance of two resistors R1 and R2:
| Combined
resistance of two resistors in parallel: |
R = | R1 × R2 |
| R1 + R2 |
For more than two resistors connected in parallel a more difficult equation must be used. This adds up the reciprocal ("one over") of each resistance to give the reciprocal of the combined resistance, R:
| 1 | = | 1 | + | 1 | + | 1 | + ... |
| R | R1 | R2 | R3 |
The simpler equation for two resistors in parallel is much easier to use!
Note that the combined resistance in parallel will always be less than any of the individual resistances.
Resistor values are measured in ohms. A thousand ohms is written as 1k to eliminate all the zeros. The k represents three zeros. A million ohms is represented by 1M. Therefore; 1000 ohms = 1k ohm and 1000k ohms = 1M ohm. Since resistors are so small their value is marked by a color code.
Resistance http://www.kpsec.freeuk.com/resistan.htm
RESISTOR COLOR CODES - Resistors use color coded stripes to indicate their value in ohms. 0=Black, 1=Brown, 2=Red, 3=Orange, 4=Yellow, 5=Green, 6=Blue, 7=Purple, 8=Gray, 9=White. To see how these colored stripes are used to indicate a resistors value click >> HERE.

A capacitor
is a device that stores an electrical charge when a potential difference
(voltage) exists between two conductors which are usually two plates separated
by a dielectric material (an insulating material like air, paper, or special
chemicals). Capacitors block DC voltages and pass AC voltages.
They are used as filters, AC coupling capacitors and as by-pass capacitors.
They are also used in conjunction with resistors and inductors to form tuned
circuits and timing circuits. A capacitors value C (in Farads) is
dependent upon the ratio of the charge Q (in Coulombs) divided by the V (in
volts). Common capacitors come in values of microfarads or Pico
farads. Often you will have to convert between Pico farads and micro
farads. A chart is provided below to assist in the conversion. For
a list of capacitor terms defined: Click
HERE. Measuring
capacitance requires a capacitance meter. This is separate piece of test
equipment. There are attachments for multimeters that allow measurement
of capacitance directly. Also read this tutorial on how to
test capacitors.
CAPACITOR Value Conversions:
Some capacitors may be marked in micro farads and others of the same capacitance value marked in Pico farads. One Pico farad equals one micro-micro farad. You may need to make conversions between the two equivalents.

Inductors
are usually made with coils of wire. The wire coils are wound around
iron cores, ferrite cores, or other materials except in the case of an air
core inductor where there is no core other than air. The inductor
stores electrical charge in magnetic fields. When the magnetic field
collapses it induces an electrical charge back into the wire. Inductors
are associated with circuit capacitance and can form a tuned circuit and
resonate at a particular frequency. Two coils close to one
another, as they are in a transformer,
literally transfer charge from one coil to the other. This is called mutual
inductance.

Ferrites are roughly divided into two groups. Those with permeabilities up to 850 are usually made from nickel-zinc material and have high volume resistivity ranging from 1x105 to 1x108. Higher permeability ferrites are usually made from manganese-zinc material and have volume resistivity ranging from 0.1x102 to 1x102. Iron powder cores are usually color coded and have very high volume resistivity. An initial test of the material can be made by checking the dc resistance between opposite faces/sides of a core. Low readings indicate a high permeability material. If you can measure inductance at a low frequency (10-100kHz), wind 10 turns of wire on the core and measure the inductance. You can then work back from the ferrite material formula and calculate the AL value, which can be compared with the tables of known cores of the same physical dimensions and so come up with a reasonable match. If 10 turns does not give a measurable reading try 20 or 30 turns.
RF power rating can be roughly checked by using two exactly similar cores each wound with the same primary and secondary turns (say 10 turns each on primary and secondary) and then connecting the cores back to back as shown. This arrangement provides a 1:1 equivalent so that the transmitter sees the correct load. Losses are doubled by using two transformers, but this does not matter for the test. Set the transmitter to the desired frequency and reduce the rf power output to a minimum. Increase the power output in small steps (say 5 -10W per step) holding each setting for 30 seconds then checking the temperature of each transformer. The transformers should only get warm to touch but NEVER hot. When the final temperature of each transformer has reached about 40 deg.C you can say that you have reached the power limit for that particular core. Some cores will get hot at very low power. You have to make a value judgment about the core physical size versus the power rating achieved.

Now that you have a good background in electricity you can move on to learning about electronics. Electronics puts a knowledge electricity to useful work. Electronics applies electrical current flow to circuits that include current and voltage amplifiers. The amplifiers can be constructed from glass "tubes" containing metal elements, transistors, or integrated circuits. A circuit containing wire conductors, resistors, capacitors, inductors and amplifiers can be configured in many ways to build various electronic circuits like oscillators, digital logic circuits, computer circuits, and much more. An oscillator by the way is just an amplifier with some of the output fed back into the input. Sounds like a perpetual motion machine but it isn't as the amplifiers power supply is providing the additional energy that is lost in the circuit.

Instructor's Manual for Malvino...
Experiments for Electronic Principles...
Excellent/Easy to Comprehend/Succinct, April 2, 2000
| Reviewer: Bonnie Pereida from USA |
I think the book is outstanding because it explains transistors better than any other book I have ever read. Rather than a heavy use of formulas, Malvino relies on concrete explanations of the physical mechanism behind transistor action. On this foundation he then goes on to explain op amps, active filters, and many other advanced topics in the absolute clearest possible way.

Do you need math skills to understand electronics? Yes! All sciences including electronics (a division of physics) requires a certain understanding of mathematics. If you are interested in electronics only as a hobby then general math may be all you will need, to get by. If you are serious about becoming an electronic technician then you will need at least a basic understanding of algebra and and be able to use and make graphs. Electrical engineers need advanced mathematics training through calculus.
Why, you may ask? Basic electronics involves the use of equations. For example, Ohms law requires a basic knowledge of algebra to fully understand it and to be able to use it effectively. Electronic technicians will use Ohms law and other algebraic formulas frequently in typical day's work. Some knowledge of trigonometry would be helpful. Electrical engineers need to know how to calculate various rates of change in electrical parameters in a quick and relatively simple manner. Without the appropriate skills at your level of interest you will be greatly handicapped in your work. There are substitutes for many situations such as pre-printed charts, databases, cookbook circuits, and internet resources. But they may not quite serve your current purpose and will take time to research and find. It is best to obtain basic math skills to a level required by your specific work.

Scared
of calculus?
Scared of calculus symbols? No need to be as they are not meant to scare
you. They are really very simple once you know how to think about them and
know what they represent. For example, often you will see the symbol d
or perhaps dx in a formula.
Well, d simply means a small amount of something.
So, dx simply
means a small amount of whatever x represents. Don't try to multiply the
two (d
and x),
they are not meant for that, just think of dx
as a small amount of x, period. The symbol dx
is called a differential. Also, you might have seen this
symbol,
called
an integral.
Now that is scary, right? No, not any more because I know it is simply a tall
skinny S. Now how can a tall skinny S
scare anyone? If you think of
as meaning "the sum
of" (the word sum starts with an S)
well, that isn't scary either. I know that 4 is the sum of
2 + 2 already. Let's say you wanted to add up all the little bits of x and
determine the sum of all the dx's
you have. Now putting these
two symbols together,
dx
simply represents "the
sum of",
all
the
"little
bits of x"
that
you have.
This
process is often called integration. Integral calculus involves adding up
little bits of things. A better definition might be, "the part
of calculus that deals with integration and its application in the solution of
differential equations and in determining areas or volumes etc." For
more information and explanation of the definitions of integral and differential
calculus see this page - HERE
- and more HERE.
So how does calculus help us in electronics? The whole purpose of calculus is to make very difficult calculations easier. Yes, sometimes down right easy or usually at least somewhat easier. Most people think calculus is designed to make simple calculations difficult to impossible. But that is only because they really don't speak or understand calculus. It is sort of a foreign language. Learn to understand the language like we did above and calculus gets a lot easier. One example is calculating a transformer rate of change in output voltage at any one given instant. A much easier problem to solve if you use calculus. Who dreamed this calculus stuff up any way? If you want to read about the history of calculus go HERE. If you want another clear explanation of calculus read this - HERE.

Understanding CapacitanceInductance Formulas - Science Forums and Debate
A
function is something whereby you can put in some variable and get a different,
dependant variable out. So, if f(x)=2x-3, you can put in some value, say 6, and
get f(6)=2(6)-3=9.
Differentiation of a function is the generation of another function for which
the "y-value" (value of the dependant variable at a given
"x-value," or independant variable) of the second is equal to the
gradient, or slope, of the first.
For example, take the function y=f(x)=x^2. For any given x, there is a y that is
equal to x^2. The derivative of this function happens to be f1(x)=2x, meaning
that for a given point on the original curve, its slope can be represented by
2x. So, at x=4, f(x)=4^2=16, and its slope at that point, f1(x)=2(4)=8, or 8
units up for every 1 unit over.
The dy/dx means instantaneous change in y divided by instantaneous change in x.
An explanation: Slope is measured by change in y divided by change in x. So
between two points on a curve, the y-value of the second minus the y -value of
the first, all divided by the x-value of the second divided by the x-value of
the first, will give you the slope of the straight line between those two
points, also called the secant. But we want the slope at a point, which poses
some problems. How can there be any change at one point? Well, there can't,
really, but what we can do is find the change between two points which are
closer to one another than any finite distance. We can determine through algebra
that as you make the distance between them smaller and smaller, the change in y
over change in x gets closer and closer to some definite ratio, which is the
"limit" as the distance between them "approaches zero."
Thus, the "dy/dx" is that ratio at an infinitely small distance,
thereby effectively being the slope at one point.Understanding CapacitanceInductance Formulas - Science Forums and Debate
If it's an upper case sigma then that means the sum of a sequence.
It's
got everything to do with integrals. An integral is the sum of the rectangles
under the curve, change in x (width) times height, the change in width
approaches zero and the number of rectangles approaches infinity. Sums are where
integrals come from. It's basically "the sum of all y-values."

These
scripts may be used to simulate long transmission structures using the
frequency-domain method, which for linear systems is acknowledged as
the "gold standard" against which other simulation
technologies are measured. These scripts provide incredible control
over every parameter of simulation. They may be re-programmed to suit
almost any need. The scripts are provided in MathCad syntax, and also
in the form of .pdf files in case you want to just see the equations
so you can port them to another brand of mathematical spreadsheet.

Digital electronics is based on electronic switches. A circuit is either on or off represented by the presence of a voltage or not or in some cases two different voltages. A string of on or off conditions are made to represent numbers. These are usually binary numbers but could be based on a variety of mathematical bases. For example, "Hexadecimal" or a base of 16. But the most common is binary. Any number can be represented in a binary based system with a series of ones' and zero's (voltage on/off conditions). Here is a short table of some binary numbers and their decimal equivalents. The binary numbers place values from right to left as shown in the table are; one, two, four, and eight. So, binary 1111 is the same as adding 1+2+4+8 from right to left and that equals 15. See the samples below then study the chart.
1 1 1 1 = 15 binary 1 0 0 1 = 9 binary 1 0 1 1 = 11 binary
8+4+2+1 = 15 decimal 8+0+0+1 = 9 decimal 8+0+2+1 = 11 decimal
| DECIMAL= | BINARY | DECIMAL = | BINARY |
| 0 | 0000 | 8 | 1000 |
| 1 | 0001 | 9 | 1001 |
| 2 | 0010 | 10 | 1010 |
| 3 | 0011 | 11 | 1011 |
| 4 | 0100 | 12 | 1100 |
| 5 | 0101 | 13 | 1101 |
| 6 | 0110 | 14 | 1110 |
| 7 | 0111 | 15 | 1111 |

Digital Projects: http://www.eleinmec.com/category.asp?3
These basic concepts are the building blocks for more sophisticated configurations of digital electronic integrated circuits. Today digital integrated circuits combine hundreds and thousands of switches per IC package. It is not necessary to know exactly what the internal circuitry is but you must know the fundamentals to understand how to use the IC's together to build digital equipment. Our computer industry today depends upon many people knowing and using these same basic fundamentals.

EIA 1956 Video Resolution Chart for printing

Television means "seeing at a distance". It may be described as a system for the conversion of light rays from still or moving scenes and pictures into electric signals for transmission or storage, and subsequent reconversion into visual images on a screen.
Basically the image formed by the camera lens is focused on a light sensitive material that is scanned in horizontal lines with each line following closely beneath it. The light intensity (and color) is converted into an electrical signal and transmitted over the air or through cables to a receiver. The "TV" receiver converts the electrical signals back into scan lines traced on a cathode ray tube (CRT). The fluorescent material on the face of the CRT is activated by the CRT's scanning electron beam to re-form the picture.
