# How do you figure the watts of a 110 volt pump that is 135 hp and has an amp draw of 54?

Yes, power = voltage x current = 54 x 110 = 5940 watts. But the odd thing is the rated horsepower. I was taught that one horsepower = 746 watts, so 135 hp = 100,000 watts. Are you certain that the pump is rated at 136 horsepower? Or can anyone else address the discrepency? W=volts X amps; therefore W= (110)(54)

## Related Questions Voltage of the pump (12) multiplied by the current draw = the watts used. This would be 12 watts if the current was 1 amp, 24 watts if the current is 2 amps, and 36 watts if the current is 3 amps, and so on... Answer Generators usually always go by watts. To figure this all you do is take(volts x Amps) = watts. You know the volts (220) then look on the pump for the amp rating and then multiply them and you will have your watts. Then get a generator that is rated for this amount for continuos operation not peak watts. Hope this helps. Divide the power rating (in watts) by the voltage (in volts). So if you use a 100 watt light bulb in a typical 110 volt lamp then it will draw 100/110 = .91 amps of current. Or plug a 1500 watt electric heater into a 110 volt wall socket and it will draw 1500/110 = 13.6 amps of current. Remember that watts are voltage x current(amps) The number of watts you can get from a 48V battery will depend on how many amps the battery can deliver and how much the load can draw. They will use the same amount of power. A 100 watt bulb will use 100 watts. If a bulb is rated at 100 watts and is specified as a 120 volt bulb, if you apply the 120 volts, it will draw 0.83 amps. Volts times amps equals watts. If you have a bulb rated at 100 watts and is specified as 12 volts, if you apply the 12 volts, it will draw 8.3 amps. No, if you check the amperage of the 120 volt unit it will draw twice as much as the 240 volt one. Your power bill is based on watts. W = Amps x volts. Say the 240 volt A/C draws 6 amps, 6 x 240 = 1440 watts. Now the 120 volt A/C draws 12 amps, 12 x 120 = 1440 watts. Depends on the size of the LED light and the voltage applied. An example is an LED 24 volt globe light that pulls 8 watts which draw 0.333333 amps. Take an LED 120 volt light bulb draws 12 watts and will pull 0.1 amps. The same bulb at 240 volts wil draw 0.05 amps. it really depends on the watts and voltage applied. An average would be about 0.1 amps.
