A transistor is operated in common emitter configuration at constant collector voltage ( V _ c =1.5 ~V ) such that a change in the base current from (100 A ) to (150 A ) produces a change in the collector current from 5 mA to 10 mA. The current gain (( ) ) is:-

Options

  1. A50
  2. B67
  3. C75
  4. D100

Correct answer

D. 100

Step-by-step solution

Current gas = = I_C I_B aligned & = (10-5) mA (150-100) mA = 5 10⁻³ 50 10⁻¹⁶ & =10 C aligned
