Best Answer

Watts = Amps x Volts x Power Factor.

Power Factor = 1 for resistive loads and gets smaller for inductive loads like motors.

Assuming home voltage of 120 Volts and a PF = 1 your answer is 400/120 = 3.33 amps.

400 volts x 45 amps?

Multiplying 400 volts by 45 amps would give you a power output of 18000 watts, which is equivalent to 18 kilowatts (kW).


How many watts equals one AMP at 400 volts?

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.

How many watts are in 3 amps?

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


How many amps will a 400 watt heater cartrige draw at 240 volts?

How many amps is 400 watt in 240 volt?

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


Which is bigger between .5 amp and .400mA?

.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.
