INTRODUCTION: - Electro Tech Online
... The nature of this solution is that the current supplied by the 5-V power supply is nearly constant; this means that as the load current decreases the current is shunted through the zener diode. The increased current through the zener diode causes a corresponding increase in the voltage across the z ...

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.
