Which formula represents Ohm's Law?

Ohm's Law is defined by the relationship between voltage, current, and resistance in an electrical circuit. The correct formula for Ohm's Law is represented as voltage (V) being equal to the product of current (I) and resistance (R), expressed as V = I x R.

This relationship means that the voltage across a conductor between two points is directly proportional to the current flowing through it, with the proportionality constant being the resistance of the conductor. Thus, if you increase the resistance while keeping the current constant, the voltage will increase. Conversely, if you increase the current while keeping the resistance constant, the voltage will also increase. This fundamental principle is essential for understanding electrical circuits and their behavior in various applications, including those relevant to radiology and medical imaging equipment.

Understanding this law is crucial for anyone working with electrical systems, as it enables practical calculations and predictions about circuit behavior, which can relate to the safe and effective use of radiologic equipment.
