The apparent power in an electrical circuit is a function of which two quantities?

Apparent power in an electrical circuit, represented as S and measured in volt-amperes (VA), is calculated by the product of the voltage across the circuit and the current flowing through it. This relationship can be summarized by the formula: S = V x I, where V is the voltage and I is the current.

The concept of apparent power encompasses both the active power, which does real work in the circuit, and the reactive power, which is stored and released by inductors and capacitors. Notably, while resistance, capacitance, and inductance are important for understanding circuit behavior, they do not directly define apparent power as a combination of quantities.

In this context, voltage and current are the fundamental quantities that determine the apparent power, making it clear why they form the basis of this calculation. The other options, while they mention different electrical properties, do not accurately represent the primary variables that compose apparent power in the same direct manner.
