Single Phase Electric Power Calculator

Calculate Single Phase AC Power (Watts)

Volts
Amperes
(0 to 1)
A typical power factor for purely resistive loads is 1.0; for inductive loads (motors), it's usually between 0.7 and 0.95.
Effortlessly calculate single-phase electric power (Watts) with our online tool. Input voltage, current, and power factor to determine power output for residential and commercial AC circuits. Ideal for electricians, engineers, and DIY enthusiasts.

Formula:

The formula for single phase electric power is:

P = V × I × PF

  • P = Power in Watts
  • V = Voltage in Volts
  • I = Current in Amperes
  • PF = Power Factor (dimensionless, typically between 0 and 1)

This formula helps you understand the true power consumed by an AC circuit, considering not just voltage and current, but also the phase difference between them.
