What does Ohm's Law state about the relationship between voltage, current, and resistance?

Ohm's Law defines the relationship between voltage (V), current (I), and resistance (R) in an electrical circuit. It states that the voltage across a conductor is directly proportional to the current flowing through it, provided the temperature remains constant. The mathematical expression of this law is V = IR, where V represents voltage, I represents current, and R represents resistance.

This equation highlights that for a constant resistance, an increase in voltage will lead to a proportional increase in current. This fundamental principle allows electrical engineers and technicians to calculate one variable when the other two are known, making it essential for analyzing and designing electrical circuits.

Understanding Ohm's Law is crucial for predicting circuit behavior, troubleshooting electrical issues, and ensuring safe and effective designs in electrical systems.
