Inductive Reactance Calculator
Calculate inductive reactance in AC circuits
About this calculator
An inductive reactance calculator determines the opposition that inductors present to alternating current (AC) in electrical circuits. This tool is essential for electrical engineers, technicians, and students working with AC circuit analysis, filter design, and power systems. By calculating inductive reactance (XL), you can predict how inductors will behave at different frequencies, enabling proper component selection and circuit optimization. Understanding inductive reactance is crucial for designing transformers, motors, chokes, and various AC applications where inductors play a key role.
How to use
Enter the inductance value in henries (H) and the frequency in hertz (Hz) into the calculator. The tool will automatically compute the inductive reactance using the formula XL = 2πfL, where f is frequency and L is inductance. The result shows the reactance in ohms (Ω), indicating how much the inductor opposes AC current flow.
Frequently asked questions
What is inductive reactance?
Inductive reactance is the opposition an inductor offers to alternating current flow, measured in ohms and increasing with frequency.
How does frequency affect inductive reactance?
Inductive reactance increases linearly with frequency - higher frequencies result in greater opposition to current flow through the inductor.
What's the difference between resistance and reactance?
Resistance opposes both AC and DC current equally, while reactance only opposes AC current and varies with frequency.
