Which law describes the relationship between voltage, current, and resistance in a circuit?

The correct answer is based on 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. Mathematically, this relationship can be expressed as V = I × R, where V represents voltage, I stands for current, and R denotes resistance.

This law is fundamental in electronics because it helps in calculating one of the three parameters if the other two are known. Understanding this relationship is crucial when designing and analyzing electrical circuits, as it allows one to predict how changes in voltage or resistance will affect the current flowing through the circuit.

While Kirchhoff's Law deals with the principles of current and voltage in more complex networks, Faraday's Law pertains to electromagnetic induction, and Maxwell's Equations describe the behavior of electromagnetic fields, they do not specifically define the direct relationship among voltage, current, and resistance as outlined by Ohm's Law.
