Electrical Current Calculator.
Estimate single-phase or three-phase current from kilowatts, voltage and power factor.
Single-phase current = P / (V × pf). Three-phase current = P / (√3 × V × pf). Local arithmetic only. This is a quantity or geometry estimate, not a code check and not a substitute for a licensed professional.
- Current
- 21.73913 A
- Apparent power
- 5 kVA
Single-phase current = power / (voltage × power factor). Power is entered in kilowatts.
How to use Electrical Current Calculator
Choose the supply, then enter power in kilowatts, voltage and power factor.
How it works
Estimate single-phase or three-phase current from kilowatts, voltage and power factor. Single-phase current = P / (V × pf). Three-phase current = P / (√3 × V × pf). Local arithmetic only. This is a quantity or geometry estimate, not a code check and not a substitute for a licensed professional.
Example
5 kW on a 230 V single-phase supply at unity power factor.
