When a camera uses a flash, a fully charged capacitor discharges through an inductor. In 4 * seconds must the 0.100-A current through a 2.00-mH inductor be switched on or off to induce a 500-V EMF.
When a Capacitor is connected to a circuit with Direct Current (DC) source, two processes, which are called "charging" and "discharging" the Capacitor
