The input resistance of a CE amplifier is

5 \mathrm{k \Omega}

and the load resistance is

20 \mathrm{k} \Omega

. If the current gain is 100 then mutual conductance of the transistor used is

View answer and explanation

Correct option: C

20 \times 10^{-3} \Omega^{-1}

Option C (

20 \times 10^{-3} \Omega^{-1}

) is correct because the mutual conductance is the ratio of the current gain to the input resistance.
