Ohm's Law

Ohm's Law is a fundamental law in electrical engineering that describes the relationship between voltage, current, and resistance in an electrical circuit. 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. In other words, the higher the voltage, the higher the current, and the higher the resistance, the lower the current.
