Question

What is the effect on capacitance on disconnecting a parallel plate capacitor filled with air from AC source. Is it same as DC source or different?

Open in App

Solution

Effect is not same for both Ac and DC ..
because frequency in DC is 0 so capacitor only conducts for too small time while in Ac it conducts.
After removing in DC it's works as earlier but in Ac behaviour will be change.
So effect is not same.
