A transistor operating in common emitter configuration

\&

change in base current from

200\, \mu {A}

250 \,\mu {A}

produces change in collector current from

10 \,{~mA}

15 \,{~mA}

. The current gain is

View answer and explanation

Correct option: D

100

Option D (100) is correct because the current gain is the ratio of the change in collector current to the change in base current.
