Current gain β A C in common emitter mode of transistor is Options: A . &nbsp βAC=△IC△IB,VC=constant B . &nbsp βAC=△IB△IC,VC=constant C . &nbsp βAC=△IC△IE,VC=constant D . &nbspβAC=△IE△IC,VC=constant

Answer: Option A : A It is β A C = △ I C △ I B , V C = c o n s t a n t Collector voltage is to be kept a constant.

Current gain βAC in common emitter mode of transistor is

Question - Current gain

β_{A C}

in common emitter mode of transistor is

Options:

A . βAC=△IC△IB,VC=constant

B . βAC=△IB△IC,VC=constant

C . βAC=△IC△IE,VC=constant

D . βAC=△IE△IC,VC=constant

Answer: Option A
:
A
It is

β_{A C} = \frac{△ I_{C}}{△ I_{B}}, V_{C} = c o n s t a n t

Collector voltage is to be kept a constant.
