Capacitive Reactance Calculator
Calculate capacitive reactance, ideal RMS current, angular frequency, and susceptance from frequency, capacitance, and voltage.
Formula
Xc = 1 / (2 pi f C).
About the Capacitive Reactance Calculator
Calculate capacitive reactance, ideal RMS current, angular frequency, and susceptance from frequency, capacitance, and voltage. This tool keeps the requested measurements separate and applies the named method instead of substituting an unrelated general estimate.
How the Capacitive Reactance Calculator Works
Capacitance is converted from microfarads to farads before angular frequency determines opposition to sinusoidal AC.
Formula
Xc = 1 / (2 pi f C).
The calculation runs in your browser. Values are validated for required ranges, compatible units, and method-specific restrictions before results are displayed.

Accuracy and Limitations
The ideal model excludes ESR, ESL, leakage, tolerance, dielectric loss, transients, and voltage or ripple ratings.
Keep units consistent, use measurements that represent the actual situation, retain full precision during the calculation, and round only the final answer. Professional decisions may require current official rules, field measurements, laboratory methods, or specialist review.
