What is the relationship between voltage, current, and resistance defined by Ohm's Law?

Ohm's Law establishes a fundamental relationship between voltage (V), current (I), and resistance (R) in an electrical circuit. The correct formula from this law is expressed as V = I x R. This means that the voltage is equal to the product of the current flowing through a conductor and the resistance of that conductor. It demonstrates how an increase in either the current or the resistance will result in a proportional increase in voltage, which is essential for understanding how electrical circuits function.

In practical terms, if you know the current flowing through a circuit and the resistance present, you can easily calculate the necessary voltage to maintain that current. This principle is widely applicable in electronics and electrical engineering, allowing for the design and analysis of efficient and effective electrical systems. Understanding this relationship is crucial for troubleshooting circuit problems and for designing circuits that meet specific electrical specifications.
