The current gain of a transistor in common emitter configuration is 80 . The resistances in collector and base sides of the circuit are 5 and 1 k respectively. If the input voltage is 2 mV , the output voltage is

Options

  1. A4 V
  2. B0.4 V
  3. C0.8 V
  4. D8 V

Correct answer

C. 0.8 V

Step-by-step solution

aligned & =80, R _ c =5 k , R _ B =1 k & ~V _ I =2 mV aligned Now, V _ o V _ I = R _ C R _ B V _ o =2 10⁻³ 80 5 1 =0.8 ~V
