2 5264Can u explain : how capacitor act when the supply is given is a.c and d.c. I know that when d.c supply is given then the capacitor charges and becomes open circuited. But please say about when a.c is given. I have seen that when a.c supply is given ,it charges and discharges, But when we plug in capacitor to our daily supply and take it out ,then we join those wires spark will appear,which seems charge is present ,but when a.c is given it should charge and discharge
