Which unit measures resistance as per Ohm's Law?

The unit that measures resistance according to Ohm's Law is Ohms. Ohm's Law defines the relationship between voltage (V), current (I), and resistance (R) in an electrical circuit, expressed as V = I × R. In this relationship, resistance is quantified in Ohms, which is the standard unit of measurement in the International System of Units (SI).

When a current flows through a conductor, the resistance determines how much voltage is needed to push the current through. Therefore, Ohms serve a critical role in understanding how different materials conduct electricity and how circuits function. Knowing this relationship helps wastewater operators, who often work with various electrical systems within treatment plants, to troubleshoot and maintain equipment effectively.
