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 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. Ohm's Law can be expressed with the formula ( V = I \times R ), where ( V ) represents voltage, ( I ) represents current, and ( R ) represents resistance.

Understanding Ohm's Law is crucial for analyzing electrical circuits, as it helps predict how changing one of these variables will affect the others. For instance, if the resistance in a circuit decreases while the voltage remains constant, the current will increase. This relationship is foundational for designing and troubleshooting electrical systems.

The other options represent different concepts in physics. Kirchhoff's Law pertains to the conservation of charge and energy in electrical circuits, Faraday's Law deals with electromagnetic induction, while Poiseuille's Law relates to fluid dynamics and the flow of liquids in tubes. These laws serve distinct purposes and do not define the relationship among voltage, current, and resistance as clearly as Ohm's Law does.
