With the capacitor in parallel, there is now an additional source of energy, which can take up some/all of the burden of supplying current to the inductive load (when it resists changes in current till it sets up its field), after which the source takes over again and recharges the capacitor.
That is, since our total impedance stays the same as before, we still end up drawing the exact same amount of apparent power as before! So, we win absolutely nothing with this approach to power factor correction. With a parallel capacitor, our load always sees the full voltage VS V S anyway.
The capacitor is connected in parallel with the loaf to avoid an unwanted voltage drop. However an appropriate capacitor in parallel with an inductive load cancels out the reactive power, and the combined load has a power factor equal to 1, thereby minimizing current drawn from the source.
This is referred to as “unity power factor”. Adding a capacitor in parallel with the coil will not only reduce this unwanted reactive power, but will also reduce the total amount of current taken from the source supply.

In summary, the textbooks recommend adding a capacitor in parallel to an RL load in order to compensate for the lagging power factor produced by the inductor. This is because the capacitor acts as a resonant circuit with the inductive load, accumulating the back EMF from the inductor and feeding it back when the voltage reverses. This helps to ...
