Famous scientist quote:
"What then is electricity?  This is at once an important and a difficult question.  It interests the lay as well as the scientific mind.  Most people who ask it never doubt the existence of electricity.  They expect a description of it - and enumeration of the peculiarities and powers of this wonderful thing.........Electric and magnetic attractions followed the same law as gravitational attraction; no wonder men thought the simple assumption of action at a distance sufficient to explain these phenomena, and to trace them back to their ultimate intelligible cause."  Heinrich Rudolph Hertz (1857-1894)

2.  TYPICAL TRANSISTOR CIRCUIT -  This is a silicon transistor circuit showing typical voltage values.   When the forward base/emitter voltage is 0.6 to 0.7 V, the transistor is silicon.   Germanium transistors will have a forward base/emitter bias voltage of 0.2 to 0.3 V   This is a silicon transistor because 2.6 base volts minus 1.9 emitter volts equal a forward bias of 0.7 volts indicating a silicon transistor.

At this point you should have more questions and want to learn more about how transistor circuits work, how to design your own transistor circuits and build electronic equipment.  Therefore; the next step would be to study the material in the following links.  From this study you will be on your way to learning more about transistor amplifier bias arrangements, the importance of impedance matching, transistor specifications, and transistor parameters.
