Konvertera Watt till Volt OmedelbartWatts to Volts

Accurately convert power to voltage for DC, AC single-phase & three-phase circuits. Supports current-based and resistance-based calculations.

Calculate using:

Power

Current

⎓

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

∿

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

≋

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

3k W	3,000 V	600 V	300 V	200 V	150 V
5k W	5,000 V	1,000 V	500 V	333.3333 V	250 V
10k W	10,000 V	2,000 V	1,000 V	666.6667 V	500 V

Vad är formeln för att konvertera watt till volt?

För en DC-krets, spänning (V) = effekt (W) ÷ ström (A).
