Question

In p-n transistor circuit, the collector current is `10 mA`. If `90%` of the holes reach the collector, find emitter and base currents.

Answer 1

Here,`I_c=10mA`, If `I_(e)` is the ammeter current, then
`I_c=90/100I_(e)`
or `I_(e)=100/90I_e=(100xx10)/90=11.11mA`
Base Current, `I_b=I_(e)-I_c=11.11-10`
`=1.11mA`
