Question

My machine takes 450 to 500 ampers during running.kindly tell me how much KWh my machine consumes?

Answer 1

The kWhr can't be determined without the voltage.

P = I E

Answer 2

Your question doesn't make sense. A kilowatt hour is a unit of energy equivalent to using one kilowatt for one hour.

Your machine uses 0.45-0.5 kW. It would use a kilowatt hour in two hours. Over a day it would use 12 kWh.

Answer 3

consumed power is,

P=V*I=220*(450~500)-------->our home supply is run on 220V

   =99000~110000 watt hrs

  =99~110 kw

if your consumption is in one hour then above mentioned power is consumed in one hour.

Answer 4

kWh is kW x hours

In order to compute kW, we need to know the voltage, current and assume a power factor.

kW = ___ volts x ____ amps x √3 x PF

volts = phase-to-phase voltage

amps = line current (450 to 500 amps)

PF = assumed power factor (typical range is 0.80 to 0.95)
