How to Convert Watts to Volts
The formulas behind each calculation mode
⎓
DC Circuit
Using Current
V = P ÷ I Voltage equals power divided by current
Using Resistance
V = √(P × R) Voltage equals square root of power times resistance
Example: 100 W ÷ 5 A = 20 V
∿
AC Single Phase
Using Current
V = P ÷ (PF × I) Voltage equals power divided by power factor times current
Using Resistance
V = √(P × R) Same resistance formula applies
Example: 1300 W ÷ (0.9 × 12 A) ≈ 120.37 V
≋
AC Three Phase
Line-to-Line
V = P ÷ (√3 × PF × I) Divide by √3 × power factor × current
Line-to-Neutral
V = P ÷ (3 × PF × I) Divide by 3 × power factor × current
Example: 5000 W ÷ (1.732 × 0.8 × 10 A) ≈ 360.84 V
