The amplification factor of a triode is 50 . If the grid potential is decreased by 0 .20 V , what increase, in plate potential will keep the plate current unchanged?

Options

  1. A5   V
  2. B10   V
  3. C0.2   V
  4. D50   V

Correct answer

B. 10   V

Step-by-step solution

μ = Δ V p Δ V g ⇒         Δ V p =   - μ × Δ V s = - 50 - 20 = 10   V
