# Capacitive Reactance calculator

The Capacitive Reactance Calculator is a free online tool that shows the capacitor's impedance in an electrical circuit. The capacitive reactance calculator tool speeds up the calculation and displays the capacitive reactance in seconds.

### Capacitive Reactance Definition and Formula

The capacitive reactance is defined as a complex impedance of the capacitor whose value varies with the applied frequency. The effect of reactance in a circuit is caused by a constant change in voltage, which causes the inductor or capacitor to react.

The formula for capacitive reactance is as follows:

**Capacitive Reactance = 1/(2πfC)**

- Where, C be the capacitance.
- f is the frequency.

The capacitive reactance formula can also be written as: **X = 1 / (ω * C),**

- where, ω= 2 *π* fis theangular frequency of the current.

### Capacitive Reactance Calculation Example

**Question 1:** Calculate the capacitive reactance of a 200nF capacitor at the frequesncy of 4kHz.

**Solution:**

Consider the problem, we have

Capacitance C is200nF

Frequency, f is 4kHz

The value ofπ is 3.14

Capacitive reactance formula is 1/(2πfC)

Capacitive reactance =1/(2(3.14)(4kHz)(200nF))

Capacitive reactance = 198.94367886486916Ω

Therefore the capacitive reactance is198.94Ω(ohms)

### FAQs on Capacitive Reactance Calculator

**1. What does capacitive reactance imply?**

The resistance to a voltage change across an element is known as capacitive reactance. The signal frequency (or angular frequency) and capacitance are inversely related in capacitive reactance.

**2. What is the formula used to calculate the capacitive reactance?**

The formula for capacitive reactance is as follows: Capacitive Reactance = 1/(2πfC)

Where

- C be the capacitance.
- f is the frequency.

**3. How to use the capacitance reactance?**

If you know the capacitance value (C) and the frequency of the signal travelling through it (f), you can use our capacitive reactance calculator to figure out the impedance of a capacitor. The capacitance can be expressed in farads, microfarads, nanofarads, or picofarads. The unit options for frequency are Hz, kHz, MHz, and GHz.

**4. What is the formula for calculating capacitance?**

The formula is used to calculate capacitance by dividing electric charge by voltage: C=Q/
