Calculate current (in amps) from power (in watts) and voltage (in volts) using the fundamental electrical formula
Calculate amperage from power and voltage
I = P ÷ V
Current = Power ÷ Voltage
This calculator uses the formula I = P ÷ V to calculate current.
Where:
To use this calculator, simply enter the power value and voltage value, then click the "Calculate Current" button to get the result.
If a device has a power of 1000W and voltage of 220V:
Current = 1000W ÷ 220V ≈ 4.55A
