# Capacitive Reactance Calculator

If you want to find the electrical resistance produced by a capacitor in an AC circuit, you can use our capacitive reactance calculator.

In physics, a complicated **capacitor's impedance** where the **amount of current changed concerning** the **applied frequency** is known as **capacitive reactance**. Whereas, reactance is the current's flow opposition in the circuit element that occurred due to capacitance/inductance. The SI unit used to measure capacitive reactance is ohms (same as resistance). The value of capacitive reactance relies on the applied voltage frequency of the capacitor's value. X is used to symbolize reactance.

## Formula of Capacitive Reactance Calculator

To know how to calculate capacitive reactance manually, you can use the formula listed below:

X_{c}= 1/(2πfC)

**Where,**

C = Capacitance

f = Frequency

2π = 6.283

**Note:**

To know more about it, you can use our Capacitive Reactance Definition.

### Example

For a more transparent and precise understanding of a concept and to comprehend how to find capacitive reactance, let us solve an example below:

Suppose a circuit has a capacitor of 220nF, supplying a current at the frequency of is 20kHz, then determine the capacitive reactance value of a capacitor.

**Given data**

Capacitance = C = 220nF = 220 × 10^{-9}F

Frequency = f = 20 kHz = 20 × 10^{3}Hz

**To Find**

Capacitive reactance = ?

**Solution**

To find out the capacitive reactance of a capacitor, we will use the formula listed below:

X_{c}= 1/(2πfC)

Putting values in the formula:

X_{c}= 1 / (6.283) × (20×10^{3}Hz) × (220×10^{-9}F)

X_{c}= 723.4 Ω
