Which law describes the relationship between current, voltage, and resistance?

Ohm's Law is the fundamental principle that describes the relationship between current, voltage, and resistance in an electrical circuit. It states that the current flowing through a conductor between two points is directly proportional to the voltage across the two points and inversely proportional to the resistance of the circuit. This can be mathematically expressed as V = I × R, where V is the voltage, I is the current, and R is the resistance.

Understanding Ohm's Law is crucial for analyzing simple circuits, as it allows one to calculate the required voltage for a specific current given a certain resistance, or conversely, to determine how much current will flow at a given voltage and resistance.

In contrast, Kirchhoff's Law deals with the principles of current and voltage in complex circuits involving multiple paths and nodes. Faraday's Law relates to electromagnetic induction, and Newton's Law pertains to motion and force, making them unrelated to the basic relationship between current, voltage, and resistance.
