In a common base transistor circuit, the current gain is 0.98. On changing the emitter current by 5.00 mA, the change in collector current is

A

0.196 mA

B

2.45 mA

C

4.9 mA

D

3.1 mA

Text Solution

Verified by Experts

The correct Answer is:
C
`alpha=0.98,I_(e)=5 mA, I_(c)= ?`
`alpha=(I_(c))/(I_(e))`
`therefore I_(c)=alphaI_(e)=0.98xx5=4.9` mA
