re Difference in kWH and kW?
The difference between kW and kWh is that;- kWh is a measure of energy whereas kW is a measure of power or more simply, the rate at which energy is generated or used.
Unfortunately, it is not immediately obvious from the term "kW" that it is a rate of energy usage. But a watt is defined as one Joule per second. ie. 1 W = 1 J/s or, 1kW = 1000 J/s
Therefore if you have a motor which is rated at 2kW (2000 J/s) and you run it for 1 hour, the total amount of energy used in that period is;- (2000 J/s * 3600 s) = 7200000 J = 7.2 MJ, which is the same as (2kW * 1hr) = 2kWh.
