If the plate resistance oftriode valve is 13 × 1 0 6 Ω and amplification factor is 21 . The mutual conductance will be

For triode valve, amplification factor, μ = r p × g m Here, r p = 13 × 1 0 6 Ω , μ = 21 , g m = ? ∴ g m = r p μ = 13 × 1 0 6 21 = 1.6 × 1 0 − 6 mho

If the plate resistance oftriode valve is $13 \times 1 0^{6} Ω$ and amplification factor is 21 . The mutual conductance will be

Options:

Answer:

Solution:

For triode valve, amplification factor, $μ = r_{p} \times g_{m} Here, r_{p} = 13 \times 1 0^{6} Ω, μ = 21, g_{m} = ? ∴ g_{m} = \frac{μ}{r _{p}} = \frac{21}{13 \times 1 0 ^{6}} = 1.6 \times 1 0^{- 6} mho$
