In a CE transistor, a change of 8.0 ~mA in the emitter current produces a change of 7.8 ~mA in the collector current. What change in the base current is necessary to produce the same change in the collector current?

Options

  1. A200 A
  2. B50 A
  3. C100 A
  4. D150 A

Correct answer

A. 200 A

Step-by-step solution

aligned & I _ E = I _ C + I _ B & I _ E =8 ~mA , I _ C =7.8 ~mA & I _ B = I _ E - I _ C =8-7.8=0.2 ~mA =200 A aligned
