Total or apparent power required by an inductive device consists of which components?

The total or apparent power required by an inductive device is measured in volt-amperes (VA). This total power has two main components: active power (measured in kilowatts, kW) and reactive power (measured in kilovolt-amperes reactive, kVAR). The relationship between these components can be expressed through the equation for apparent power (S), which is the vector sum of active power (P) and reactive power (Q).

The correct answer highlights the significance of both kW and kVAR, providing insight into how they combine to inform us about the overall power consumption of inductive devices. This understanding is crucial in managing power systems, as it allows for the assessment of energy efficiency and helps with the calculation of power factor.

While the other options reference important aspects of electrical theory—such as basic relationships among voltage, current, and power—they do not effectively describe the components of total or apparent power in context to inductive devices. Hence, focusing on kW and kVAR directly addresses the question regarding the nature of power in inductive loads.
