Vedclass · Answer

(B) Given:$Current \, amplification \, factor \, (\beta) = 60$$Input \, resistance \, (R_i) = 1 \, k\Omega = 1000 \, \Omega$The transconductance $(g_m)$ of a transistor is defined as the ratio of the current amplification factor to the input resistance:$g_m = \frac{\beta}{R_i}$Substituting the given values:$g_m = \frac{60}{1000} \, \Omega^{-1}$$g_m = 0.06 \, S = 6 	imes 10^{-2} \, S$Thus, the transconductance is $6 	imes 10^{-2} \, SI \, units$.

$A$ transistor has a current amplification factor of $60$. In a $CE$ amplifier, input resistance is $1 \, k\Omega$ and output voltage is $0.01 \, V$. The transconductance is (in $SI$ units)
