Ohm's Law is a fundamental principle in electrical engineering that relates voltage, current, and resistance. The correct interpretation of this law states that voltage is equal to the current flowing through a conductor multiplied by the resistance of that conductor. This relationship can be expressed mathematically as:

Voltage (V) = Current (I) x Resistance (R)

This formula underpins much of circuit analysis and allows for the calculation of one of the three variables if the other two are known. Understanding this relationship is essential for diagnosing electrical circuits, predicting how circuits will behave under different conditions, and designing effective electrical systems.

The other options do not accurately reflect Ohm's Law. For example, some suggest a division rather than multiplication, which can lead to misunderstandings about how these electrical properties interact with each other. Understanding the correct formulation is vital for foundational knowledge in nursing and any field that involves basic electrical concepts.
