For transistor action which of the following statement are correct
(a) base emitter and collector regions should have smilar size and doping concentrations
(b) the base region must be very thin and lightly doped
(c ) the emitter junction is forward biased and collector junctions is reverse biased
(d)both the emitter junction as well as the collector junction are forward biased

Options

A. (4),(1)
B. (1),(2)
C. (2),(3)
D. (3),(4)

Answer

C

Explanation

In active state :
Emitter- base junction `to` FB, and
Collector -base junction `to` RB
as well as base region must be very thin and lightly doped.
