How many watts are in 1.25KW?

Answer 1

Watts are a function of volts times amps. A power factor is involved in motor loads, but we will discount that for now.

You could have 1.25 amps flowing in a high voltage line representing a very large number of watts due to the high voltage, but lets assume we are speaking of a two wire, (hot and neutral) (the grounding wire would not be included in the calculation since it will carry no current in this example) 120volt circuit feeding say a small kitchen mixer.

120 volts times 1.25 amps = 150 watts

If this were a residential 240 circuit, (2 hot wires) the watts would be double, (1.25 times 240=300 watts

Answer 2

1250 watts
