Which of the following describes the relationship between voltage, current, and resistance?

The relationship between voltage, current, and resistance is described by Ohm's Law. This fundamental principle in electrical engineering 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. The formula representing this relationship is often expressed as ( V = IR ), where ( V ) is voltage, ( I ) is current, and ( R ) is resistance.

Understanding this relationship is key for linemen when designing circuits and ensuring safe and efficient operation of electrical systems. This principle aids in troubleshooting electrical issues, calculating the expected current flowing through a circuit for a given voltage source, and determining the necessary specifications for components like resistors.

The other laws mentioned serve different purposes: Kirchhoff's Law pertains to the conservation of charge and energy in electrical circuits, Faraday's Law relates to electromagnetic induction, and Newton's Law primarily deals with the motion of objects. Therefore, while they are important in their respective contexts, they do not describe the specific relationship between voltage, current, and resistance as Ohm's Law does.
