# RLC Parallel Circuit

## Important Formula

What do the formula symbols mean?

## Impedance

Unit
Impedance is the magnitude of the complex resistance $$Z$$. This formula gives the total impedance of a driven resistor-coil-capacitor parallel circuit, in short: RLC parallel circuit.

## Inductance

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

## Capacitance

Unit
Capacitance of the capacitor connected to the RLC parallel circuit.

## Electrical Resistance

Unit
Resistance of a resistor connected to the RLC parallel circuit.

## Angular frequency

Unit
The angular frequency $$\omega = 2\pi \, f$$ indicates the frequency $$f$$ at which the LRC parallel circuit oscillates. The frequency $$f$$ is specified, for example, by the frequency of the applied AC voltage.

An RLC parallel circuit consists of a resistor $$R$$, an inductance $$L$$ and a capacitance $$C$$, which are connected in parallel. These three electrical components form an electrical circuit in which the current can take different paths through the resistor, the coil and the capacitor.
