The transfer ratio of a transistor is 50 . The input resistance of the transistor when used in the common emitter configuration is 2 k . The peak value of the collector AC current for an AC input voltage of 0.02 V peak is

Options

  1. A200 A
  2. B0.01 mA
  3. C0.25 mA
  4. D500 A

Correct answer

D. 500 A

Step-by-step solution

Given, =50, R=2 k =2 10^3 , aligned & V_b=0.02 ~V & i_c=? aligned Input current, i_b= V_b R_b = 0.02 2000 =10⁻⁵ ~A Also, current gain, = i_c i_b aligned i_c & = i_b=50 10⁻⁵ ~A & =500 10⁻⁶ ~A =500 A aligned
