Reactance Calculators

What is a Reactance Calculator?

A Reactance Calculator is a tool used to determine the reactance of an inductor or capacitor in an AC circuit. Reactance is the opposition that inductors and capacitors provide to alternating current (AC) and is measured in ohms (Ω).

There are two types of reactance:

1. Inductive Reactance (XL) – Opposition to AC by an inductor.
2. Capacitive Reactance (XC) – Opposition to AC by a capacitor.

Why Use a Reactance Calculator?

• Circuit Design: Helps engineers calculate impedance and design AC circuits.
• Frequency Analysis: Reactance changes with frequency, so it's useful for radio, audio, and power applications.
• Resonance Calculations: Essential for tuning circuits like filters, antennas, and oscillators.
• Component Selection: Ensures proper inductor or capacitor values for circuit performance.

When is a Reactance Calculator Used?

• In AC circuit analysis for power and signal transmission.
• For RF (radio frequency) and antenna design to match impedance.
• In filter and amplifier design for controlling frequency response.
