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:

Answer:

Solution:

Amplification factor of a triode, $μ = \frac{p}{Δ V _{g}}$ $\Rightarrow Δ V_{p} = - μ \times Δ V_{S} = - 50 (- 20) = 10 V$
