Which of the following describes the relationship between power, voltage, and current according to Ohm's Law?

The relationship between power, voltage, and current is defined by Ohm's Law, which states that power is equal to the product of voltage and current. This can be represented mathematically as:

Power (P) = Voltage (V) × Current (I)

This formula indicates that as either voltage or current increases, the power consumed in a circuit also increases, assuming the other variable remains constant. Understanding this relationship is fundamental in electrical engineering and utility services as it helps in calculating the power needs of various electrical devices.

The other options do not accurately reflect the relationship defined by Ohm's Law. For instance, expressing power as current divided by voltage or voltage divided by current leads to indistinguishable or incorrect units and meanings. Similarly, power equating to current times resistance does not capture the interplay between voltage and current directly, but rather ties into the broader context of electrical circuits through the use of resistance, highlighting a different aspect of circuit behavior.

Recognizing the correct formulation is crucial for effective analysis and application in utility services as it directly informs power management and energy efficiency strategies.
