The light flash discharges the capacitor in a tiny fraction of a second. Why does charging take longer than discharging? This question and a number of other phenomena that involve charging and discharging capacitors are discussed in this module.

The time constant τ for an RC circuit is τ=RC . When an initially uncharged capacitor in series with a resistor is charged by a dc voltage source, the capacitor asymptotically approaches the maximum charge. As the charge on the capacitor increases, the current exponentially decreases from the initial current.

Even if the capacitor and inductor were connected by superconducting wires of zero resistance, while the charge in the circuit is slopping around between the capacitor and the inductor, it will be radiating electromagnetic energy into space and hence losing energy.

Further suppose that you remove the capacitor from the battery.
