Does a capacitor have resistance?
While an ideal capacitor in theory does not have any resistance, practical capacitors do exhibit resistance in the forms of ESR and leakage resistance. A capacitor does have some resistance in practical sense. Whenever a capacitor gets charged, current flows into one of the plates and current flows out of the other plate and vice versa.

This is the resistance due to the leakage current that flows through the dielectric material of the capacitor when a voltage is applied across it. Ideally, this should be very high, indicating very low leakage current, but in real capacitors, it is finite.
