Question

If in a triode value amplification factor is $20$ and plate resistance is $10k\Omega$, then its mutual conductance is

• A. $2$ $milli$ $mho$
• B. $20$ $milli$ $mho$
• C. $\left(1/2\right)$ $milli$ $mho$
• D. $200$ $milli$ $mho$

Answer 1

Answer: (A)

$2$ $milli$ $mho$

Mutual conductance $g_m=\frac{\mu }{R_P}$
$=\frac{20}{10\times {10}^3}=2\times {10}^{-3}=2$ $milli$ $mho$
