Q. The plate resistance of a triode is $2.5 \times 10^{4}\Omega$ and mutual conductance is $2 \times 10^{- 3}\ mho$. What will be the value of amplification factor
A) 50
B) $1.25 \times 10^{7}$
C) 75
D) $2.25 \times 10^{7}$
Explanation
(a) $\mu = r_{p} \times g_{m} = 2.5 \times 10^{4} \times 2 \times 10^{- 3} = 50$
