Question

In a N-P-N transistor circuit, the collector current is 10 mA. If 90% of the electrons emitted reach the collector, the emiitter current (I _E ) and base current (I _B ) are given by

(A) I_E = 1mA; I_B = 11 mA

(B) I _E = 11 mA; I_B = 1 mA

(C) I_E = –1 mA; I_B = 9 mA

(D)I _E = 9 mA ;I_B = –1 mA

Answer 1

(B) I_E = 11 mA;I_B = 1 mA
