Question

Identify and explain about the diode whose characteristics curve is:

Answer 1

It is curve from $P-N$ Junction diode

$Capacitance\propto \frac{1}{\sqrt{ReverseBias}}$

As the reverse bias increases so the width of junction increases

By, logic

$\downarrow C=\frac{{ϵ}_{o}A}{d\uparrow }$ this is a simple example.
