The transfer ratio of a transistor is 50. The input resistance of the transistor when used in the common-emitter configuration is 1 KΩ. The peak value for an ac input voltage of 0.01 V peak is
A
100 μA
B
0.01 Ma
C
0.25 mA
D
500 μ A
Answer
500 μ A
Explanation
Solution
ic=βib=β×RiVi=50×10000.01=500×10−6A=500μA
