Multiplying 400 volts by 45 amps would give you a power output of 18000 watts, which is equivalent to 18 kilowatts (kW).
One ampere (A) at 400 volts (V) is equal to 400 watts (W). This is because power (in watts) is calculated by multiplying voltage (in volts) by current (in amperes). So, in this case, 1A x 400V = 400W.
The conversion of watts to amps at a fixed voltage is governed by the equation Amps = Watts/Volts for example 12 watts/12 volts = 1 amp for a US example, a food mixer with a 400 watt motor on a 120 volt supply 400/120 = 3.33amps, fit a 5amp fuse
To calculate the amperage, you can use the formula: Amps = Watts / Volts. In this case, a 400-watt heater cartridge at 240 volts would draw 1.67 amps.
For calculation purposes there are 746 watts in one horsepower.

It depends on the supply voltage watts = current in amps times the supply voltage

calculation for Watts is = volts X amps P=IE P= Power(WATTS) I = Current(AMPS) and E = Voltage(VOLTS). So: I = P/E and E = P/I therefore: 1 watt = 1 ampere x 1 volt If you havea 240 volt lamp that is drawing .5 amp then it is using 120 Watts
.5 amps equals 500 ma, which is much larger than .400 ma.If you meant between .5 amps and 400 ma, then again, .5 amps equals 500 ma, which is larger than 400 ma by a factor of 100 ma.
led tvs 55" or bigger especially manufactured after 2009 use around 350-370 watts plus 15w a piece on the speakers generally around 400 watts pulling 3.5 amps
About 298,400 watts.
For calculation purposes there are 746 watts in one horsepower.
While there's no set number for the best systems 400 to 1000 watts is normal for high end systems.
