In transistor, a change of `8.0 mA` in the emitter current produces a change of `7.8 mA` in the collector current. What change in the base current is necessary to produce the same change in the collector current ?A. `50 muA`B. `100 muA`C. `150 muA`D. `200 muA`

Answer» Correct Answer - B
`Deltai_(e)=Deltai_(c)+Deltai_(b)`
`implies 8=7.8+Deltai_(b) implies Deltai_(b)=0.2 mA=200 muA`
