Dumb question: if we have monthly demand kwh from power company, how do we convert this number to Amp? Thanks.
This conversion can be done (in a couple steps) Understand that kWh is a measurement of work done in time. Where amps is a measurement of rate of flow of electric current. They are measuring two different things.
If you have the TOTAL kW (not kilo-watt hour) usage then you can figure it this way:
Kilowatts to amps conversion
The current (I) in amps is equal to the 1000 times the power (P) in kilowatts, divided by the voltage (V) in volts:
I = 1000 ? P / V
So amps are equal to 1000 times kilowatts divided by volts.
amps = 1000 ? kilowatts / volts
Or
A = 1000 ? kW / V
Kilowatts to amps example
What is the current in amps when the power consumption is 0.33 kilowatts and the voltage supply is 110 volts?
I = 1000 ? 0.33kW / 110V = 3A
If you want to figure how much kW per Hour:
Kilowatts to kilowatt-hour calculation formula
The energy (E) in kilowatt-hour is equal to the power (P) in kilowatts, times the time period (t) in hours:
E(kW?h) = P(kW) ? t(h)
So
kilowatt-hour = kilowatt ? hour
Or
kW?h = kW ? h
Example
What is the energy consumption when the power consumption is 5 kilowatts and for time duration of 3 hours?
E = 5kW ? 3h = 15 kW?h
