Answer Posted / guest
a trnsistor is a semiconductor device in which the current
flows through semiconductor materials .it has 2 types of
1.NPN transistor 2.PNP transistor .the three constituient
portion of a transistor are emitter,collector and
base .emitter is the one which is heavly doped(either
positive or negative)with moderate area which emits
majority charge carriers. base is the one which is very
lightly doped & very thin region ,it passes majority
carriers from emitter to collector. collector is the one
whose doping lies between emitter and base, it disipate
more heat..
