To find the current a device pulls, you divide its power by the voltage, and this calculator does exactly that. For a DC circuit or a resistive AC load, amps equal watts divided by volts. For a real AC load with a power factor, such as a motor, the current is watts divided by voltage times the power factor, so the tool includes a power factor field defaulting to one. Knowing the current matters for choosing a fuse, sizing wire, and checking that a circuit or power strip is not overloaded. For example a 1200 watt appliance on a 120 volt supply draws about ten amps, which is why many kitchen circuits are rated at fifteen amps. Enter the power, the voltage, and a power factor if needed, then read the current instantly. Everything runs locally in your browser, so it is fast and private.
