Question

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

Answer 1

Correct Answer - 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
