A 750 watt heater does not use any hours in its formula to obtain wattage from values.
The formula you are looking for is I = W/E. Amps = Watts/Volts.
Approx 1 horse power
watt=750kva*pf/1000
6.25 Amps when using standard 120 Volts
volts times amps equal watts. So 12 volts times ? amp equals 1.5 watts. The current is 1.5/12 amps, which is 1/8 amp.
125V
Must know two parts of the equation before the other can be answered. However, assuming there is 110vac applied, then the answer would be about 1,320 watts.
It depends of the voltage applied. You'll find the answer using the formula P=V.I, where P is the power in watts, V is the voltage in volts and I is the current in amp (in the case, equal to 1 amp)
That depends on the voltage available. We assume 120 volts. Then amperage equals power divided by voltage. Amp. = 900 watts / 120 volts = 7.5 amps.
volts times amps equal watts. So 12 volts times ? amp equals 1.5 watts. The current is 1.5/12 amps, which is 1/8 amp.
To power your speakers, and to ensure that your amp has enough power to power your subwoofers, you would need at least an amp of 750 watts true power.

750 watts per horse power20 x 750 = 15,000 watts / 220V = 68A68 amps at 220 volts
0.75 kW
Assuming the same voltage and power factor for the two motors. Watts = Volts x Amps x PF so the power of 1000 A motor is Watts = 1000 x V x PF and the 750 A motor is Watts = 750 x V x PF. So (Watts for 1000A) / (Watts for 750A) = 1.33 This means the 1000 A motor uses about 33% more electricity than the 750 A motor.

1 HP = 750 watts / 5250 divided by 750 = 7
A VA is a volt-ampere, or volt-amp, and a kilo (K) is one thousand. This makes a KVA a kilovolt-ampere, or kilovolt-amp. If we have 1,000 volt-amps, and one volt times one amp is equal to one watt (W), which it is, 1,000 volt-amps is equal to 1,000 watts, or 1 KW. All that said, 1 KVA is equal to 1 KW.Sometimes in an ac system, the watts is less than the volts times the amps, and in that case the watts is equal to the volts times the amps times the power factor. The power factor is less than one. The power factor for a typical electric motor is 0.7, so then there are only 700 watts in a kVA.
