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:
- Tuning Circuits
- Oscillators circuits.
Oscillator circuits are likely the most common. These can convert DC signal to AC signal.
