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

The relationship between voltage, current, and resistance is known as Ohm's Law. This fundamental principle in electronics 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. In formula terms, this is expressed as V = I × R, where V represents voltage, I represents current, and R represents resistance.

Understanding Ohm's Law is critical for analyzing electrical circuits, as it provides a clear mathematical framework for predicting how changes in one of the variables (voltage, current, or resistance) affect the others. For instance, if the voltage in a circuit increases while resistance remains constant, the current will also increase proportionally.

The other options refer to different concepts in electrical engineering. Kirchhoff's Law deals with the conservation of charge and energy in electrical circuits. Faraday's Law pertains to electromagnetic induction and how a change in magnetic field can induce a voltage in a conductor. Equivalent Resistance is a calculation used to determine the total resistance of a circuit, particularly in series and parallel configurations, but does not express a direct relationship between voltage, current, and resistance.
