IP  is known as the power component because it is
in phase with the voltage and corresponds to power loss in the circuit It’s clear from this analysis that if we want to improve power factor,
we must completely neutralize the lagging wattless current Iq by an
equal leading wattless current I¢q This can be done by connecting
a capacitor of appropriate value in parallel so that Iq and I¢q cancel
each other and P is effectively Ip V Example 7
