A transistor is a semiconductor device which conduct and insulate current and voltage.
-
Transistors are mostly used in every electronic devices.
-
Transistors function as switch and amplifier. It amplifies and switch electric power and electronic signals.
-
The small amount of current is applied to one pair of terminals to control the larger signal at the another pair of terminals.
-
Transistors was developed in the year 1947 by three American physicists John Bardeen, Walter Brattain and William Shockley.It is most useful invention in the history of science.

-
Base
-
Collector
-
