Capacitor in an AC Circuit

Plot a graph ...

Question

Plot a graph showing variation of capacitive reactance with the change in the frequency of the $A C$ source.

Open in App

Solution

Capacitive reactance

$X_{c} = \frac{1}{2 π f C}$

$f = \frac{1}{2 π X_{c} C}$

$X_{c} = C a p a c i t i v e R e a c t a n c e$

$f = f r e q u e n c y$

Graph between capacitive reactance and change in frequency of AC source is shown in above figure.
