Question

in a comm on base configuration a=0.95and IE =1M. Then the value of IC is​

Answer 1

Answer:

Correct option is

B

0.05mA

Given :

I

e

=1mA,

α=0.95

We know,

α=

I

e

I

c

I

c

=αI

e

I

c

=(0.95)(1)

I

c

=0.95mA

For transistor,

I

b

=I

e

−I

c

I

b

=1−0.95

I

b

=0.05mA
