Resonance of an RLC circuit refers to the condition when the voltage across the inductor is the same as the voltage across the capacitor, or ({ V }_{ L } = { V }_{ C}).

The two basic properties of a capacitor are that it can store electric charges and that it passes higher-frequency AC currents more easily. However, in high-frequency ranges, the capacitor begins to reveal a different side. This is because the subtle inductive component within the capacitor becomes more dominant, and the capacitor alone begins to behave like a …

Resonance of a circuit involving capacitors and inductors occurs because the collapsing magnetic field of the inductor generates an electric current in its windings that charges the capacitor, and then the discharging capacitor provides an electric current that builds the magnetic field in the inductor. This process is repeated continually. An analogy is a mechanical pendulum, and both are a form of simple harmonic oscillator.
