Which law describes the fundamental relationship in electrical circuits?

Ohm's law precisely describes the fundamental relationship between voltage, current, and resistance in electrical circuits. It 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 mathematically represented as ( V = I \times R ), where ( V ) is the voltage, ( I ) is the current, and ( R ) is the resistance. Understanding this law is crucial for troubleshooting and designing electrical circuits, making it a foundational principle in both theoretical and practical applications within the field of aviation mechanics and electrical engineering. Other laws, such as Faraday's law, primarily focus on electromagnetic induction, while Newton's laws pertain to motion and physical forces, and Kepler's laws describe planetary motion—not the behaviors of electrical circuits.
