Our advanced Wattage to Amperage Calculator helps you quickly determine the current (amps) from power (watts) and voltage. Ideal for sizing wires, fuses, and circuit breakers in DC, single-phase, and three-phase AC systems. Perfect for electricians, engineers, and DIY enthusiasts. Get accurate conversions and ensure electrical safety with ease!
Formula:
The Wattage to Amperage calculation depends on the electrical system type (DC, single-phase AC, or three-phase AC).
For DC Circuits:
I (Amps) = P (Watts) / V (Volts)
For Single-Phase AC Circuits:
I (Amps) = P (Watts) / (V (Volts) × PF (Power Factor))
For Three-Phase AC Circuits:
I (Amps) = P (Watts) / (√3 × V (Volts) × PF (Power Factor))
Where:
- I = Current in Amperes (Amps)
- P = Real Power in Watts
- V = Voltage in Volts
- PF = Power Factor (ranging from 0 to 1; 1 for resistive loads or DC)
- √3 ≈ 1.732 (for three-phase systems)
