Answer Posted / ankit
when a coil or capacitor is connected to an AC power
supply, the coil or capacitor stores electrical energy
during one-fourth of an AC cycle. But then during the next
quarter-cycle, the coil or capacitor dumps all the stored
energy back into the distant AC power supply. Ideal coils
and capacitors consume no electrical energy, yet they
create a significant electric current. In other words, if
your electrical appliance contains inductance or
capacitance, then electrical energy will periodically
return to the power plant, and it will flow back and forth
across the power lines. This leads to an extra current in
the power lines, a current which heats the power lines, but
which isn't used to provide energy to the appliance. The
coil or capacitor causes electrical energy to
begin "sloshing" back and forth between the appliance and
the distant AC generator. ACTIVE power is what what you pay
for.apparant power is the vector sum of active and reactive
power
