Vedclass · Answer

(B) In a diode valve,the saturation current is limited by the number of electrons emitted from the cathode per second. Saturation occurs when all electrons emitted by the cathode are collected by the anode (plate). This state is reached more easily when the plate voltage is high (to pull all electrons) and the filament current is relatively low (limiting the total emission to a level that the plate can easily collect).

$V_g$ (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 a diode valve,the state of saturation can be obtained easily by
