Ohm’s Law Explained

Ohm's Law explains the relationship between voltage, current, and resistance by stating that the current through a conductor between two points is directly proportional to the potential difference across the two points. A law is relating the voltage difference between two points, the electric current flowing between them, and the resistance of the path of the current. Mathematically, the law states that V = IR, where V is the voltage difference, I is the current in amperes, and R is the resistance in ohms. For a given voltage, higher resistance entails lower current flow.
