The current of transistor in common emitter mode is 49. The change in collector current and emitter current corresponding to the change in the base current by `5.0 muA`m will be :-

Options

A. `245muA,250muA`
B. `240muA,235muA`
C. `260muA,255muA`
D. None of these

Answer

A

Explanation

Given `beta=49`
current gain `beta=(triangleIC)/(triangleIB), where `triangleI_(c)` is change in collector current
and `triangle I_(B) is base current
`traingleI_(c)=betatriangleI_(B)=498xx5=245mua`
`triangleI_(E)=triangleI_(C)=(245+5)muA=2450muA`
