Vedclass · Answer

(D) In a triode valve,the grid is typically maintained at a negative potential relative to the cathode to control the plate current $(I_p)$.As the grid voltage $(V_g)$ becomes more negative,the plate current decreases for a given plate voltage $(V_p)$.Conversely,as the grid voltage becomes less negative (closer to $0 \ V$),the plate current increases for the same plate voltage.In the given graph,curve $D$ shows the highest plate current for a given plate voltage,meaning it corresponds to the least negative (or highest) grid voltage.Since the grid is maintained between $0 \ V$ and a negative potential,the curve $D$ corresponds to $V_g = 0 \ V$.

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

In the figure,four plate characteristics of a triode at different grid voltages are shown. The difference between successive grid voltages is $1 \ V$. Which curve will have the maximum grid voltage and what is its value?
