What is the change in the collector current , in a transistor of a.c. current gain 150, for a `100 mu A` change in base current ?

Explanation

Data supplied ,
`beta = 150`
`Delta I_(B) = 100 xx 10^(-6) A`
`beta = (Delta I_(C))/(Delta I_(B))`
`DeltaI_(C) = beta xx Delta I_(B) = 150 xx 100 xx 10^(-6) = 0.015 A`
