Volts don't make power. Watts do. Watts = (volts) x (amps) 1 horsepower = 746 watts (Doesn't matter if the source is AC, DC, or a combination of both.)
4.5~5.3
6 volts
It will take 36 volts to make 12 amps go through 3 ohms of resistance. Ohm's law states that the current in amperes is equal to voltage over resistance.
12 volts DC.
24 Volts.
You require about 24 volts to power the windshield wiper.
It takes 0.7462 kW to equal one horsepower.
If the 100 amps is powered by 10 volts, you have 1 kw, or 1000 watts. watts = volts X current The 'k' simply means kilo, or thousand.
There is no difference in horsepower. The manufacturer builds the air conditioner. Engineers calculate and tell the manufacturer how much power is going to be required to make it operate. Smaller units will probably use lower voltage with lower horsepower to operate efficiently. The bigger the unit will take higher horsepower to operate. There comes a point when single phase, low voltage use will not work due to the unavailability of high horsepower, low voltage motors. At this point three phase systems are used with higher voltages to operate the motors. Examples of a 10 HP motor at different voltages. Single phase - 115 volts 100 amps, 230 volts 50 amps. Three phase same HP - 200 volts 32.2, 230 volts 28, 460 volts 14 and 575 volts 11 amps. As you can see if the air conditioner needs a 10 HP motor at single phase 115 volts, a feeder supply of 100 amps would be needed. This compared to the same air conditioner using a three phase 575 volt system which draws 11 amps.
