Question

A variable frequency AC source is connected to a capacitor. Will the displacement current change if the frequency of the AC source is decreased ?

Answer 1

Displacement current = I = C*dV/dt

Increasing frequency = increasing dV/dt.

Thus dropping the frequency will drop the displacement current through the capacitor

Answer 2

Hey !!

It is noted that by dropping the variable frequency, there will be drop in displacement current through the capacitor as it carries displacement current. When the frequency decreases, amplitude of current will also decrease.

GOOD LUCK !!
