In the following common emitter configuration an n p n transistor with current gain =100 is used. The output voltage of the amplifier will be

Options

  1. A10 mV
  2. B0.1 ~V
  3. C1.0 ~V
  4. D10 ~V .

Correct answer

C. 1.0 ~V

Step-by-step solution

We know that the output voltage is given by, v₀=v_i R_L R_ B E Here, v_i=1 mV , =100R_L=10 k , R_ B E =1 k v₀=1 10⁻³ 100 10 1 =1.0 ~V
