What principle does Ohm's Law describe?

Ohm's Law fundamentally describes the relationship between voltage, current, and resistance in an electrical circuit, effectively illustrating how these three parameters interact. Specifically, 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 expressed as ( V = I \times R ), where ( V ) represents voltage, ( I ) is current, and ( R ) is resistance.

Understanding this principle is crucial for analyzing electrical circuits as it allows for calculating one of the three variables when the other two are known, which is essential for troubleshooting and designing circuits.
