In electrical terms, what does "Ohm's Law" state?

Ohm's Law is a fundamental principle in electrical engineering that defines the relationship between voltage, current, and resistance in an electrical circuit. The correct statement according to Ohm's Law is that voltage equals current times resistance. This means that if you know the current flowing through a conductor and the resistance of that conductor, you can calculate the voltage across it.

The formula is expressed as V = I × R, where V is voltage, I is current, and R is resistance. This relationship is crucial for understanding how electrical circuits function, as it allows for the calculation of one variable if the other two are known.

In contrast, the other statements do not accurately represent Ohm's Law. Power equals current times resistance is incorrect because power is defined as P = V × I, not related directly to resistance in this manner. Current equals voltage times resistance is also incorrect; it inaccurately rearranges the formula and does not follow the correct mathematical representation. Lastly, resistance equals voltage divided by current is a manipulation of Ohm's Law that is correct but not the standard way to express the original law itself.
