For a transistor I(e) = 25 mA and I(b) =...

For a transistor `I_(e) = 25 mA and I_(b) = 1mA`. The value of current gain `alpha` will be :-

A

`(25)/(24)`

B

`(24)/(25)`

C

`(25)/(26)`

D

`(26)/(25)`

Text Solution

Verified by Experts

The correct Answer is:
B
`alpha=(I_(C))/(I_(E))=(I_(E)-I_(B))/(I_(E))=(25-1)/(25)=(24)/(25)`
