The RLC circuit is an oscillating circuit consisting of a resistor, capacitor, and inductor connected in series. The resistor is always charged to a high voltage, the capacitor is charged when the resistor is turned on; the inductor when it turns off. When this circuit is connected to a load the current in the circuit will flow through various points in series each each with a voltage. When the capacitor appears to be completely charged, it is actually storing energy in its chemical structure. When this happens, any change in the current flow is resisted by the capacitor. The capacitors are not discharged when they appear to be fully charged. The voltage in the capacitor eventually causes the current to spiral around it. The result is an oscillation, or resonance.
