Enter the total capacitance and total inductance of an RLC circuit to calculate the frequency of that circuit. An RLC circuit consists of 3 components, a resistance, impedance, and a capacitance.

## RLC Circuit Formula

The following equation can be used to calculate the frequency of an RLC circuit.

F = 1 / [2π * √(L * C)]

- Where F is the frequency (Hz)
- L is the inductance (Henries, H)
- C is the Capacitance (Farads)

## RLC Circuit Definition

An RLC circuit is defined as an electrical circuit with a resistor, inductor, and capacitor.

## RLC Circuit Uses

In this case the equation can only be used when these three components are combined in a series. This would not apply if they were connected in some other way.

The three main uses for RLC Circuit are as follows:

- Filters
- Tuning Circuits
- Oscillators circuits.

Oscillator circuits are likely the most common. These can convert DC signal to AC signal.
