In the case of common emitter transistor amplifier, the ratio of collector current to emitter current is 0.96 , then the current gain ( ) of the amplifier is

Options

  1. A6
  2. B48
  3. C24
  4. D12

Correct answer

C. 24

Step-by-step solution

The common base current gain is defined as = I_C / I_E = 0.96 . The common emitter current gain relates to through the expression = / (1 - ) . Substituting the given value yields = 0.96 / (1 - 0.96) = 0.96 / 0.04 = 24 . Final answer: The current gain is 24.
