Answer Posted / puneet kapil

First of all get clerar with the term KVA and KW
KW is the real power or active power
that means the amount of power that is available to do real work.
And KVA is the apparent power,that means
only a part ogf apparent power is available to do real work
rest or remainder is simply the excess current.
Now the question arises why to mention KVA the apparent power,
if only we can use a part of it...
Answer..... the rating of electrical appliances is dependent om the amount of current they can sustain,but KW does not give the actual amount of current that electrical equipment
can carry which is given by KVA...
I hope its clear now :)
