Ohm's Law is a fundamental principle in electrical engineering that describes the relationship between voltage, current, and resistance in an electrical circuit. The law states that the voltage across a conductor between two points is directly proportional to the current flowing through it, provided the temperature remains constant. The mathematical representation of this law is:

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

This means that if you know any two of these values (voltage, current, or resistance), you can calculate the third.

Choosing the correct statement about Ohm’s Law clarifies that when we multiply current (I) by resistance (R), we arrive at the voltage (V) across the conductor. This understanding is foundational in electrical work, allowing electricians and engineers to design and troubleshoot electrical circuits efficiently.

While other options mention relationships between these electrical quantities, they do not accurately represent Ohm's Law. For instance, stating that power equals current times resistance misrepresents the power equation, which actually states that power is the product of current and voltage. Similarly, the relationships involving division or incorrect associations do not align with the original statement of Ohm's Law.
