Calculate generator current from watts, voltage, and power factor values easily.
The generator watts to amps conversion depends on electrical phase, voltage, and power factor.
For single phase generators, the formula is:
Amps = Watts ÷ (Voltage × Power Factor)
For three phase generators, the formula is:
Amps = Watts ÷ (√3 × Voltage × Power Factor)
Watts represent electrical power output. Voltage represents electrical pressure. Power factor shows efficiency.
