Yes, the displacement current will decrease if the frequency of the AC source is reduced. This is because displacement current depends on the rate of change of the electric field, which decreases with lower frequency.

A variable frequency a.c. source is connected to a capacitor. Will the displacement current change if the frequency of the a.c. source is decreased?
Yes, the displacement current will decrease if the frequency of the AC source is reduced. This is because displacement current depends on the rate of change of the electric field, which decreases with lower frequency.
