In a p-n-p transistor operating as amplifier with common emitter configurations a change in base current from `100 muA ` to `200 muA` produces to change in collector current grain of transistor

A

`12.5 xx 10^(-3)`

B

`25xx10^(-3)`

C

80

D

98

Text Solution

Verified by Experts

The correct Answer is:
C
`beta=(deltaI_(c))/(deltaI_(b))`
`=((18-10)xx10^(-3))/((200-100)xx10^(-6))=(8xx10^(3))/(100)=80`
