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 8 A sinusoidal voltage of peak value 283 V and frequency
50 Hz is applied to a series LCR circuit in which
R = 3 W, L = 25
