Which law is used to describe the relationship between voltage, current, and resistance?

Ohm's Law is the fundamental principle that defines the relationship between voltage (V), current (I), and resistance (R) in an electrical circuit. It is expressed by the formula V = I × R, indicating that the voltage across a conductor is directly proportional to the current flowing through it when the temperature remains constant. This relationship helps in calculating one of the three variables if the other two are known, enabling efficient design and analysis of electrical systems.

In contrast, Kirchhoff's Law deals with the conservation of charge and energy in electrical circuits, providing techniques to analyze complex circuits. Faraday's Law pertains to electromagnetic induction and how a changing magnetic field can induce an electromotive force in a circuit. Newton's Law, relating to motion and forces in mechanics, does not apply to electrical relationships. Understanding Ohm's Law is crucial for anyone working with electrical systems, as it serves as a foundation for circuit analysis and design.
