If `alpha and beta` are the current gain in the CB and CE configurations respectively of the transistor circuit, then `(beta-alpha)/(alphabeta)=`

A

infinite

B

1

C

2

D

0.5

Text Solution

Verified by Experts

The correct Answer is:
B
The relation between `alpha and beta` is
`" "beta=alpha/(1-alpha)`
Putting this value in the given equation, we have
`" "(beta-alpha)/(alphabeta)=(alpha/(1-alpha))/(beta*alpha/(1-alpha))=alpha^(2)/alpha^(2)=1`
