Questions
In an n-p-n transistor, the collector current is 10 mA, if 90% of the electrons emitted reach the collector, the emitter current IE and base current IB are given by
detailed solution
Correct option is D
As, collector current, IC=90100×IEwhere, lE = emitter current.⇒ 10=0.9×IE⇒ IE=11mAAlso, IE=IB+ICBase current, IB=IE−IC =11−10=1mATalk to our academic expert!
