Questions  

In an n-p-n transistor circuit, 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

a
IB=−1mA,IB=9mA
b
IE=9mA,IB=−1mA
c
IE=1mA,IB=11mA
d
IE=11mA,IB=1mA

detailed solution

Correct option is D

(4) IE=IB+IC , 0.9 IE=IC=10mA IE=11  mA,IB=IE−IC=11−10=1mA
