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, resistance, impedance, and 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)

What is an RLC Circuit?

An RLC circuit is an electrical circuit that consists of three main components: a resistor (R), an inductor (L), and a capacitor (C). These components are interconnected in a specific way to create a circuit that exhibits certain electrical properties.

The resistor is a passive component that limits the flow of electric current, converting electrical energy into heat.

The inductor, on the other hand, stores electrical energy in the form of a magnetic field when a current passes through it.

The capacitor stores electrical energy in an electric field when a voltage is applied across its terminals.

The RLC circuit is important because it allows for the study and analysis of electrical behavior in circuits with reactive components. When an alternating current (AC) is applied to an RLC circuit, the interaction between the resistor, inductor, and capacitor results in interesting phenomena.

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:

  1. Filters
  2. Tuning Circuits
  3. Oscillators circuits.

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