Ohm's Law states that the voltage across a conductor or component is directly proportional to the current flowing through it while inversely proportional to the resistance of that component. This relationship is mathematically represented as V = I * R, where V represents voltage in volts, I represents current in amperes, and R represents resistance in ohms.

This formula highlights that if you increase the current flowing through a circuit, the voltage will likewise increase, assuming the resistance remains constant. Understanding this relationship is crucial in electrical engineering and related fields, as it allows for the prediction of how changes in either current or resistance will impact the voltage in a circuit.

The other options do not accurately represent the relationship defined by Ohm's Law, which clearly establishes voltage as the product of current and resistance. Hence, they cannot be valid interpretations of this fundamental principle of electricity.
