Zener diode voltage regulator File
... Simple emitter follower series pass regulator The Zener diode will generally need a minimum of around 10mA for a small Zener to keep its regulated voltage. The resistor should then be calculated to provide the base drive current and the minimum Zener current from a knowledge of the unregulated volt ...

... In this problem you are to construct a graphical drawing of the iC – vCE characteristic of the BJT, with base current values of iB = 10 A, 20 A, 30 A, 40 A and 50 A, to estimate amplifier parameters . To simplify the problem we ignore the Early effect ; meaning the output resistance is infinite ...

History of the transistor
A transistor is a semiconductor device with at least three terminals for connection to an electric circuit. The vacuum-tube triode, also called a (thermionic) valve, was the transistor's precursor, introduced in 1907.
