[/itex]Hi I am new here
I know (correct me if wrong please ) that inductors store current in its magnetic field, and capacitors store voltage in its electric field
But, why when disconnecting a inductor charged from a DC circuit, a spark is produced at the disconnected point and it loses its energy while the capacitor not and the electricity is stored like a battery? I understand that [itex]I = \frac{V}{R}[/itex] and the spark in inductors are produced because Voltage rises to compensate the resistance when opening the circuit but, why does a capacitor voltage stay the same despite no current and infinite resistance and a inductor discharges immediately at the same circumstances?
Many thanks.
