Ohm's Law is a fundamental principle in electrical engineering and physics that relates voltage, current, and resistance in a circuit. The correct representation of Ohm's Law is articulated through the formula Voltage = Current x Resistance. This means that the voltage across a conductor is equal to the current flowing through it multiplied by the resistance of that conductor.

This relationship is crucial for understanding how electrical circuits function, allowing for the calculation of voltage when the current and resistance are known.

The other formulas mentioned do not accurately represent the relationship defined by Ohm's Law. For instance, while power is indeed related to voltage and current through the formula Power = Voltage x Current, that specific relationship does not fall under Ohm's Law. Similarly, the formulas involving resistance or current in conjunction with power do not reflect the core concept of how voltage, current, and resistance interact in accordance with Ohm's Law.
