Which of the following best describes Ohm's Law?

Ohm's Law establishes the relationship between voltage, current, and resistance in an electrical circuit. The correct formulation of Ohm's Law is: Current equals Voltage divided by Resistance. This means that if you know the voltage applied across a conductor and the resistance of that conductor, you can calculate the current that flows through it.

Using this relationship, if the voltage increases while the resistance remains the same, the current will also increase, and conversely, if the resistance increases while the voltage stays constant, the current will decrease. This direct relationship is foundational in electrical engineering, making the understanding of this law crucial for anyone working with electrical systems.

The other formulations provided do not accurately reflect Ohm's Law or are misstates in terms of relationship, thus not establishing the accurate direct interplay between the three variables (voltage, current, resistance) involved in electrical circuits.
