What does Ohm's Law state?

Ohm's Law is a fundamental principle in electrical circuits that defines the relationship between voltage, current, and resistance. The law specifically states that the voltage (V) across a conductor is directly proportional to the current (I) flowing through it, given that the temperature and material properties remain constant. This relationship can be mathematically expressed as V = I × R, where R represents resistance.

Thus, the correct interpretation aligns with the understanding that voltage equals current multiplied by resistance. This is crucial in circuit analysis, as it allows for the calculation of one parameter if the other two are known. Understanding this relationship helps in various applications, such as designing circuits and troubleshooting electrical systems. In practice, Ohm’s Law is widely used to ensure that electrical systems are operating correctly and safely.
