voltage

So in the circuit above if the voltage across the capacitor is greater than the voltage of the voltage source, Vs, the capacitor will discharge through the resistor, R, until the voltage across the capacitor equals the voltage supplied by Vs. At that point current will stop flowing through R, as there is no voltage difference across it.
