power factor to voltage calculator

Convert power factor, power, and current to voltage using V= P/(I*PF) Useful for AC circuit analysis and electrical load calculations.

power factor voltage formula

To calculate such power factor to voltage V = P / (I x PF) To determine voltage where P is power Three phase AC circuits: V = P / ( 3 days ahysPiPF).

Formula & Table Summary:

  • Single-phase: \( V = \frac{P}{I \times PF} \)
  • Three-phase: \( V = \frac{P}{\sqrt{3} \times I \times PF} \)

Units: P (W), I (A), V (V), PF (0–1).

voltage calculation from PF

A Power Factor to Voltage Calculator can calculate AC voltage in terms of power, current and power factor. In single phase systems use V = P/ (I x PF) On three-phase systems: V = P/( 3 1)PF.

Frequently Asked Questions - power factor to voltage calculator:

How to calculate voltage from power factor?

Use V = P / (I × PF) for single-phase or V = P / (√3 × I × PF) for three-phase AC.

What is power factor?

Power factor is the ratio of real power to apparent power, between 0 and 1.

Why does low PF increase voltage requirement?

Because real power is lower for the same apparent power, requiring higher voltage for the same output.

Does formula change for DC?

No, PF is 1 in DC, so V = P / I.

What units should I use?

Watts for P, amperes for I, volts for V, dimensionless PF.

How to measure PF?

Use a power meter that displays real power, apparent power, and calculates PF.

Can PF be greater than 1?

No, in practical systems PF ≤ 1.

What about reactive power?

Reactive power does not contribute to real work but affects PF and apparent power.

Is this valid for unbalanced loads?

No, formula assumes balanced loads for three-phase systems.

How to improve PF?

Add power factor correction capacitors or synchronous condensers.
