Real Reactive Apparent Power Calculator

Real Reactive Apparent Power reports real power from one operating case.

Enter values for real power

Use one consistent electrical operating case for all fields.

V

Enter rms voltage in V.

A

Enter rms current in A.

Enter power factor in the displayed unit.

How Real Reactive Apparent Power works

The calculation uses P = VI×PF; S = VI; Q = √(S²−P²). Real Reactive Apparent Power uses RMS voltage, RMS current, Power factor to report Real power. Impedance magnitude can be checked in Parallel RLC Impedance Calculator.

With the loaded values, real power evaluates to 1,886.00 W. Change only the quantity being investigated.

Inputs for Real Reactive Apparent Power

RMS voltage, RMS current, and Power factor belong to Real Reactive Apparent Power. Keep source units with rms voltage.

The preset case is instructional rather than prescriptive. Enter the applicable electrical data. Use Resonance Bandwidth Calculator.

RMS voltage
Example entry: 230 V.
RMS current
Example entry: 10 A.
Power factor
Example entry: 0.82.

Reading the Real Reactive Apparent Power result

This output represents Real Reactive Apparent Power.

Finish the selection with standard sizes, operating limits, and transient review. Use Power Factor Correction Calculator to estimate correction reactive power.

Measurement and units

Use RMS quantities unless a field explicitly asks for peak amplitude. Check prefixes on rms voltage. Continue to Inductive Reactance Calculator for inductive reactance.

Use the same unit basis and observation location in alternate cases.

Limits of this calculation

Use the displacement factor only for nearly sinusoidal current.

A complete system can contain effects that this equation does not represent. Unentered effects remain outside Real Reactive Apparent Power.
