In a transistor if collector current is ...

In a transistor if collector current is 25 mA and base current is 1 mA, then current amplification factor `alpha` is

A

`(25)/(24)`

B

`(24)/(25)`

C

`(25)/(26)`

D

`(26)/(25)`

Text Solution

Verified by Experts

The correct Answer is:
C
`beta=(I_(c))/(I_(B))=(25)/(1)=25`
`alpha=(beta)/(1+beta)=(25)/(26)`
