The relationship between voltage, current, and resistance is described by Ohm's Law, which states that voltage equals the product of current and resistance. This fundamental principle explains how electrical circuits operate: when a voltage is applied across a conductor, it creates an electric current that flows through the resistance of the conductor.

To understand this relationship, consider that voltage serves as the driving force that pushes the current through the circuit. Resistance, on the other hand, opposes the flow of current. Therefore, if you know the current flowing through a circuit and the resistance it encounters, you can calculate the voltage required to maintain that current.

This understanding is crucial in electrical engineering and many practical applications, allowing one to design and analyze circuits effectively. It also serves as a foundation for understanding more complex electrical concepts and systems.
