Quick Reference
PF
Power Factor (0-1)
√3
1.732 (approx)
Overview
Calculate electrical current (Amps) from power (Watts) and voltage. For AC circuits, power factor is included.
💡
Pro Tips
DC: I = P / V
AC Single Phase: I = P / (V × PF)
AC Three Phase: I = P / (V × PF × √3)

Fun Facts
"Home outlets in the US typically provide 15-20 Amps at 120 Volts."
"Lowering the Power Factor increases the current drawn for the same amount of real power."
Formula: I = P / V
