The amplification factor of a triode valve is 15 . If the grid voltage is changed by 0.3 V , the change in plate voltage in order to keep the current constant (in volt) is :

Options

  1. A0.02
  2. B0.002
  3. C4.5
  4. D5.0

Correct answer

C. 4.5

Step-by-step solution

aligned =15, V_g & =0 3 & = V_p V_g V_p= V_g & =15 0.3 & =4.5 ~V . aligned
