Vedclass · Answer

(B) In a triode,the plate current is determined by the number of electrons reaching the plate $P$ from the cathode $K$. When the grid $G$ is given a positive potential,it exerts an attractive force on the electrons emitted from the cathode,helping them pass through the grid mesh towards the plate. Since the plate $P$ must also be at a positive potential to attract these electrons,having both the grid and the plate at positive potentials results in the maximum flow of electrons to the plate,thereby maximizing the plate current. Therefore,the correct option is $B$.

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