RLC or LC circuit diagram
The parameters of an RLC circuit are calculated from the resistance (R), inductance (L) and capacitance (C), using known equations. For series and parallel circuits, the resistor, capacitor and inductor are connected differently, and different damping factors result.

And RLC or LC (where R=0) circuit consists of a resistor, inductor and capacitor, and can oscillate at a resonant frequency which is determined by the natural rate at at which the capacitor and inductor exchange energy. These circuits are used extensively in electronics, for example in radios and sound-producing devices, but they can also be formed unintentionally in electronic circuits, causing problems for their required operation.
