What does Ohm’s Law state?

Ohm's Law is a fundamental principle in electrical engineering and physics that describes the relationship between voltage, current, and resistance in an electrical circuit. The correct statement of Ohm's Law is that voltage equals current multiplied by resistance. This means that if you know the current flowing through a conductor and the resistance of that conductor, you can calculate the voltage across it.

This relationship can be expressed mathematically as:

Voltage (V) = Current (I) × Resistance (R)

Understanding this law is crucial for working with electrical circuits, as it helps in predicting how changes in one component will affect the others. For example, if the resistance in a circuit increases while the current remains constant, the voltage must also increase to fulfill this relationship. This principle allows engineers and technicians to design and troubleshoot electrical systems effectively.
