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:

Answer:

Solution:

$μ = 15, Δ V_{g} ∴ μ = 0 \cdot 3 = \frac{Δ V _{p}}{Δ V _{g}} \Rightarrow Δ V_{p} = μ Δ V_{g} = 15 \times 0.3 = 4.5 V .$
