​RC Circuit Calculator

The combination of a pure capacitance C in Farads and pure resistance R in ohms is called an RC circuit.

A circuit in which resistance and capacitance are connected together in a series is called an RC series circuit. RC Circuit is known as the resistor-capacitor circuit. It is also a basic electrical circuit in which resistance R of the resistor is connected in a series with the capacitor of a capacitance C.


Types of RC Circuits Calculator

There are two types of RC Circuits

  • Charging RC Circuit

  • Discharging RC Circuit

What is charging RC Circuit?

A charging RC circuit consists of:

  • A partially charged or completely uncharged capacitor

  • A resistor

  • A DC current source

What is discharging RC Circuit?

A discharging RC circuit consists of:

  • A fully-charged or partially-charged capacitor

  • A resistor

Formula of ​RC Circuit Calculator

F = 1 / (2π*R*C)


R = resistance of the resistor in Ω

C = capacitance of the capacitor in Farads

F = frequency in hertz


To calculate frequency, you can use our Frequency Calculator.


If we have a capacitance is 13F and resistance is 8Ω then calculate the frequency of an RC Circuit.

Given data

Capacitance = 13F
Resistance = 8 Ω

To Find

Frequency = ?


To get frequency, let's use the formula below:

F = 1 / (2π * R * C)

Putting values in the formula:

F = 1 / (2 * 3.14 * 13 * 8)
Frequency = 0.0015303 Hz
