Question

When the diode shows saturated current, dynamic place resistance is
(a) zero
(b) infinity
(c) indeterminate
(d) different for different diodes

Open in App

Solution

(b) infinity

Saturated current is the maximum current beyond which, there is no effect of plate voltage (V_P)
on the plate current (I_P). At this stage, dynamic resistance is infinite.
