The relationship between current, voltage, 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, it is often expressed as ( V = I \times R ), where ( V ) is the voltage, ( I ) is the current, and ( R ) is the resistance.

Understanding this relationship is fundamental in electrical circuits, as it helps in calculating one of the three parameters when the other two are known. Ohm’s Law is a cornerstone of electrical engineering and physics, forming the basis for analyzing and designing circuits.

In contrast, Faraday's Law pertains to electromagnetic induction, describing how a changing magnetic field can induce an electric current. Kirchhoff's Law deals with the principles of current and voltage in electrical circuits, known primarily as Kirchhoff’s Current Law and Kirchhoff’s Voltage Law, which help analyze circuits but do not define the direct relationship between current, voltage, and resistance. Newton's Law relates to motion and forces, which is a separate domain in physics not associated with electrical parameters.
