What describes the relationship between current, voltage, and resistance in an electrical circuit?

The relationship between current, voltage, and resistance in an electrical circuit is described by Ohm's Law. This fundamental principle states that the current (I) flowing through a conductor between two points is directly proportional to the voltage (V) across the two points and inversely proportional to the resistance (R) of the conductor. Mathematically, this is expressed as V = I × R.

Ohm's Law is crucial in understanding how electrical circuits operate, as it allows electricians and engineers to calculate one of the three variables—current, voltage, or resistance—if the other two are known. This relationship is foundational for designing and troubleshooting electrical systems, contributing to efficient and safe electrical installations.

Other laws mentioned don't specifically relate to this relationship among current, voltage, and resistance. Kirchhoff's Law focuses on the conservation of charge and energy in circuits, Faraday's Law pertains to electromagnetic induction, and Newton's Law deals with motion, not electrical properties.
