Question
The transfer ratio β of a transister is 50. The input resistance of the transistor when used in the common emitter configuration is 1kΩ. The peak value of the collector A.C. current for an A.C. input voltage of 0.01 V, is
Options
A.500 μA
B.0.25 μA
C.0.01 μA
D.100 μA
Solution
β = 
⇒ Ib = 
= 10-5
or 50 =
⇒ Ib = 50 × 10-5
= 500 × 10-6
Ic = 500μA
⇒ Ib = = 10-5 or 50 =
⇒ Ib = 50 × 10-5= 500 × 10-6
Ic = 500μA
