The relationship among voltage, current, and resistance is defined by?

The relationship among voltage, current, and resistance is defined by Ohm's Law, which 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. This relationship can be expressed with the formula ( V = I \times R ), where ( V ) represents voltage, ( I ) represents current, and ( R ) represents resistance.

Ohm's Law is fundamental in electrical engineering and physics, as it provides a basic understanding of how electrical circuits behave and enables the calculation of one of the quantities if the other two are known. This law applies to many electrical components and circuits, helping to predict how changes in voltage or resistance affect the current in the system.

Other principles, such as Faraday's Law, focus on electromagnetic induction, where a change in magnetic field can induce voltage. Tesla's Principle primarily relates to the transfer of energy using electromagnetic fields, and Coulomb's Law deals with the electrostatic interaction between charged particles. None of these laws define the straightforward relationship among voltage, current, and resistance as effectively as Ohm's Law does.
