What is the capacitor discharge load
When the switch is closed, the capacitor begins to discharge, producing a current in the circuit. The current, in turn, creates a magnetic field in the inductor. The net effect of this process is a transfer of energy from the capacitor, with its diminishing electric field, to the inductor, with its increasing magnetic field. - Download [PDF]

Charging and Discharging a Capacitor
The amount of resistance in the circuit will determine how long it takes a capacitor to charge or discharge.
