In the common-base configuration, a transistor has current amplification factor 0.95 . If the transistor is used in common-emitter configuration and base current changes by 2 A , then the change in the collector current is

Options

  1. A19 A
  2. B0.91 A
  3. C1.9 A
  4. D38 A

Correct answer

D. 38 A

Step-by-step solution

Given, =0.95 So, aligned & = 1- = 0.95 1-0.95 =19 & = = I_C I_B =19 aligned or I_C=19 2=38 A
