kW to Volts Calculator — ChiefEngineer.in

Calculate voltage from real power and current.

Reset

Formula

V = 1000·P/I (DC)
V = 1000·P/(I·PF) (1φ)
VL = 1000·P/(√3·I·PF) (3φ)

Variables

  • P — power
  • I — current
  • PF — power factor

Worked Example

Input: 2.3 kW, 10 A, PF 0.9, 1φ

Result: V ≈ 255.56 V

Assumptions & Notes

Balanced load.
