Verified by Toppr

D.C
→ After long time current in the branch containing capacitor become 0, but voltage difference and change storage is maintained.
A.C
→ capacitors in AC circuits like to pass current when the voltage across its plates is constantly changing with respect to time . Continuously charging and discharging of capacitor takes place.
