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))=(I_(C))/(I_(B))+1=beta+1`
