Question

A transistor has a base current of lmA and emitter current 100mA. The current
transfer ratio will be
A) 0.9
B) 0.99
C) 1.1
D) 10.1
А)
B)
B
C)
С
D)
D​

Answer 1

Answer:

B) 0.99

Explanation:

Given that:

Ib  = 1 mA , Ie = 100 mA

Hence,  Ic  = Ie −Ib  = 100−1 = 99 mA

Current transfer ratio is   Ie/ Ic  =  99/100  = 0.99
