Questions
In NPN transistor, electrons enter in emitter region in s. If 2% electrons are lost in base region, then collector current and current amplification factor respectively are
detailed solution
Correct option is A
Ie=1010×1.6×10−19×110−6=1.6 mA ∵I=Qtsince 2% electrons are absorbed by base, hence 98% electrons reaches the collector, i.e., α=0.98⇒Ic=αIe=0.98×1.6=1.568 mA ≈1.57 mATalk to our academic expert!
