For a transistor, the current amplification factor α is 0 . 8 . If it is connected in common emitter configuration, the change in collector current when the base current changes by 6 mA is

Options

  1. A6 mA
  2. B4 . 8   mA
  3. C24 mA
  4. D8 mA

Correct answer

C. 24 mA

Step-by-step solution

I c = α 1 - α I b = 0.8 0.2 I b = 4 I b I c = collector current I b = base current I c = 24   mA
