What does OHM's Law describe?

Ohm's Law is a fundamental principle in electronics and electrical engineering that defines the relationship between three key electrical quantities: current, voltage, and resistance. According to this law, 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 can be expressed using the formula: V = I × R, where V is the voltage, I is the current, and R is the resistance.

Understanding this relationship allows engineers and technicians to analyze and design electrical circuits effectively. It provides a basis for troubleshooting electrical issues and optimizing circuit performance, because it explains how adjustments in voltage or resistance will affect current flow. Overall, recognizing the implications of Ohm’s Law is essential for anyone working in or studying electrical systems.
