Sorry to say but KW-HR is not a unit of electricity
it is the unit by which electricity department charges our
bill the reason after that is if we put a load of 1 kw on
meter then it takes one hour to change its one reading after
one hour
remember i am asking to put only load of one KW not more
than that and after one hour only 1 KW reading will increase
that is why it is KW per Hour

Answer / rajesh

If you want to represent bulk power, you can use a bigger
unit like Megawatt hour or Gegawatt hour. (1 MWH = 1000
KWH; 1 GWH = 1000MWH).

Answer / anil bhatia

the energy meter which measure unit is desine to calculate
kwh . ie 1000 X wattes x Hrs (time consumed or used the
power).
where watts is volts X current .
voltage= is applied/given volts,
current=Amper taken by load

Answer / thuranga

Rishit's answer is also correct,
and also the another one is load is not constant for a
minute in our normal life i.e if we measure power at
12noon,that load will not be same at 12:30 pm.

So on an average the load is calculated on hourly basis for
the purpose of finding the efficiency for all day.,and also
the power consumed domestically.

A transformer has negative voltage regulation when its load PF is A zero B unity C lagging D leading
