What is the relationship between voltage, current, and resistance known as?

The relationship between voltage, current, and resistance is defined by Ohm's Law. This law 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 conductor. Mathematically, this is expressed as V = I × R, where V is the voltage, I is the current, and R is the resistance.

Ohm's Law is fundamental in understanding how electrical circuits operate, allowing for the calculation of one of these quantities if the other two are known. It is crucial for analyzing electrical components, understanding circuit behavior, and designing electrical systems.
