SUMMARY
S represents apparent power in electrical circuits, defined by the equation S = P + jQ, where P is real power and Q is reactive power. Reactive power (Q) is not wasted; instead, it circulates between the source and load, affecting the efficiency of power delivery. Power companies incur additional costs due to reactive power, as it requires larger transformers and heavier cables. Consumers are typically billed only for real power (P), while reducing reactive power (Q) is beneficial for both consumers and power companies.
