"what is the use of reactive power"
Ans: Reactive power comes from usually reactive component
of circuit such as capacitor ,inductor.Normally we calculate
real power for power calculation .That does not mean that
reactive power is useless.For example, in motor there is a
magnetizing current and without this current motor won't
rotate but interesting matter is that since motor coils are
inductive so the power from magnetizing current also
reactive power . So will u say this power is useless?
Let u want to drink milk .So drinking milk Ur main goal
.But when u drink milk u use a glass or something to hold
the milk. U can now compare reactive power as a glass,real
power as a milk and the summation of reactive and real power
is apparent power thats mean for drinking milk ,u need milk
and glass both.
