Formulas Used

DCI = P / V

No power factor needed for DC circuits.

AC 1φI = P / (V × PF)

Single-phase AC — multiply voltage by power factor.

AC 3φI = P / (√3 × V × PF)

Three-phase AC — divide by √3 ≈ 1.732.

Frequently Asked Questions

How many amps is 200 watts at 120V?

DC or resistive: 200 / 120 = 1.6667 A. Single-phase AC at PF 0.9: 200 / (120 × 0.9) = 1.8519 A.

How many amps is 200 watts at 240V?

DC or resistive: 200 / 240 = 0.8333 A. Single-phase AC at PF 0.9: 200 / (240 × 0.9) = 0.9259 A.

How many amps is 200 watts at 12V?

DC: 200 / 12 = 16.6667 A. This is common for 12V battery and solar systems.
