# Inductive Reactance Calculator

Our inductive reactance calculator can effortlessly **obtain the inductive reactance of an inductor** for you.

Within this short text, we will briefly cover:

**Inductive reactance definition**;- How to find inductive reactance using the
**inductive reactance formula**; and - Learn more about the relationship between
**impedance**and**inductive reactance**.

Let's start!

## Inductive reactance definition

**Inductive reactance ($X_{L}$)** is a property of electrical circuits that describes how inductors resist changes in current:

- If the current
**increases**, the inductor will oppose it and try to keep the current from increasing; or - If the current
**decreases**, the inductor will oppose it and try to keep the current from decreasing.

As in resistance, the units for inductive reactance are **ohms (Ω)**.

How do you find the inductive reactance value? You will need to know the inductance and the frequency of the AC signal. Let's see how together they describe inductive reactance.

🔎 See our capacitive reactance calculator to understand how the same concept applies to capacitors.

## Inductive reactance formula

The inductive reactance formula is:

where:

- $f$ is the frequency of the
**AC**signal in hertz (**Hz**); - $L$ is the inductance in henries (
**H**); and - $X_{L}$ is the inductive reactance.

💡 You can switch between units using the toggle feature next to each input in our inductive reactance calculator.

As you can see, *inductive reactance increases with frequency and inductance*. The higher the inductance or frequency, the higher the inductive reactance.

**Give it a try!** Input two different inductances in the inductive reactance calculator and see how the reactance changes accordingly.

## What is impedance? How does it relate to inductive reactance?

*Impedance* is the **total** opposition that a circuit offers to the flow of an alternating current. The impedance of a circuit is represented by the letter **Z**.

It consists of two components: *resistance* and *reactance*.

**Resistance (R)**is the*real part*of impedance and represents the opposition to current due to**resistors**(read more about this in our resistor wattage calculator); and**Reactance (X)**is the*imaginary*part of impedance and represents the opposition to current due to**inductive reactances**and**capacitive reactances**.

🙋 Our inductive reactance calculator uses **admittance** instead of impedance. Admittance is the *reciprocal* of impedance. This means it describes *how easily a circuit allows current to flow through it*.
