# 10 Best Free Online RLC Resonant Frequency Calculator Websites

Here is a list of the **best free online RLC Resonant Frequency calculator websites**. An RLC Resonant Frequency calculator or RLC Circuit calculator calculates the characteristic frequency and the Quality Factor of a circuit. This works for an RLC circuit where R stands for Resistance, L stands for Inductance, and C stands for Capacitance. The Resistance can be in parallel or in series. This does not impact the Resonant Frequency. But you get different Q Factors for a circuit in series and a circuit in parallel.

This post covers 10 websites where you can calculate the Resonant Frequency of an RLC circuit online. All these calculators take the values of Resistance (R), Inductance (L), and Capacitance (C) as input. With those inputs, you get the Resonant Frequency and Q Factor of the circuit. Some of these calculate other related terms including Damping Factor, Bandwidth, etc. The table below can you give you a brief idea of what each of these calculators calculates and what does not. You can jump to any calculator from there and read about it in detail.

### My Favorite Online RLC Resonant Frequency Calculator

**EasyCalculation.com** is my favorite website on this list to calculate RLC Resonant Frequency online. With RLC input, this calculator calculates Resonant Frequency along with Daming Factor, Q Factor, Bandwidth, and Attenuation. In the case of values that get impacted by the Resistance, it shows both values; when the circuit is in series and when it is in parallel.

You can also check out our other lists of the best free online Unit Circle Calculator websites, online F-Distribution Calculator websites, and online Chi-square Distribution Calculator websites.
