What are transistors?
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.
Transistors have three terminals:
Positive lead of transistor
Used to activate transistor
Negative lead of transistor
