# Formula Phase Shift (RLC Series Circuit) Inductance    Capacitance    Angular frequency    Electrical Resistance

## Phase angle

Unit
Phase shift indicates the angle (in degrees or radians) by which a voltage applied to the RLC series circuit lags or leads the resulting current.
• If the phase shift $$\varphi$$ is positive, then the applied voltage leads the resulting current.
• If the phase shift $$\varphi$$ is negative, then the applied voltage lags the resulting current.

## Inductance

Unit
The inductance of the coil connected to the RLC circuit.

## Capacitance

Unit
Electrical capacitance of the capacitor connected to the RLC circuit.

## Angular frequency

Unit
The angular frequency $$\omega ~=~ 2\pi \, f$$ indicates the frequency $$f$$ at which the RLC circuit oscillates. For example, the frequency $$f$$ is given by the frequency of the applied AC voltage.

## Electrical Resistance

Unit
Ohmic resistance of a resistor connected to a RLC series circuit.
