The circuit gain of transistor in a common emitter circuit is `40`. The ratio of emitter current to base current is.

A

`40`

B

`41`

C

`42`

D

`43`

Text Solution

Verified by Experts

The correct Answer is:
B
`beta =(I_(C))/(I_(B))` and `(I_(E))/(I_(B))=(I_(C)+I_(B))/(I_(B))=(I_(C))/(I_(B)) +1 =beta + 1`.
