750 Watts to Amps
750 W = 6.25 A
750 watts draws 6.25 amps on a 120-volt circuit (3.13 A at 240 V).
Step by step
- Use the formula amps = watts ÷ volts (I = P ÷ V).
- At 120 V: 750 ÷ 120 = 6.25 A.
- At 240 V: 750 ÷ 240 = 3.125 A.
For a continuous load, size the circuit so this draw is no more than 80% of the breaker rating — at least a 15 A circuit.

How it works
Current in amps equals power in watts divided by voltage: I = P ÷ V. This is exact for DC and for resistive AC loads like heaters, kettles and incandescent bulbs. Motors and some electronics on AC have a power factor below 1, which means they draw a little more current than this simple formula shows. The same appliance draws half the current at 240 V as at 120 V.
