Infinite

Vedclass · Answer

(B) The plate resistance $({r_p})$ is defined as the ratio of the change in plate voltage $(\delta V)$ to the change in plate current $(\delta I)$,expressed as $r_p = \frac{\delta V}{\delta I}$.At the saturation point,the current reaches its maximum value and does not change with further increases in voltage,meaning the change in current $\delta I = 0$.Substituting this into the formula,we get $r_p = \frac{\delta V}{0} = \infty$.Therefore,at saturation,the plate resistance is infinite.

$V_g$ (volt)	$0$	$-2$	$-4$	$-6$
$I_p$ (mA) for $V_p = 150$ $V$	$15$	$12.5$	$10$	$7.5$
$I_p$ (mA) for $V_p = 120$ $V$	$10$	$7.5$	$5$	$2.5$
