Question

For a common emitter circuit if ????ᴄ = 0.98 then current gain for
????ᴇ
common emitter circuit will be
(a) 49 (b) 98
(c) 4.9 (d) 25.5

Answer 1

Answer:

Hey!

Given that I eI c

=0.98

⇒I c

=0.98I e

So we get Ib

=I e −I c

=0.02Ie

Therefore the current gain is I bIc

= 0.02

0.98

=49

Therefore the correct option is C.

Answer 2

Explanation:

C}.4.9
