Resistance is measured in which unit?

Resistance is measured in Ohms, which is the standard unit in the International System of Units (SI) for this electrical property. Ohm's Law describes the relationship between voltage, current, and resistance, stating that the current flowing through a conductor between two points is directly proportional to the voltage across the two points and inversely proportional to the resistance. Essentially, one Ohm is defined as the resistance that allows a current of one Ampere to flow when one Volt is applied. This makes the Ohm the proper unit to quantify resistance in electrical circuits, aligning with the foundational principles of electrical engineering and physics.

In contrast, Volts measure electric potential or voltage, Amperes quantify the flow of electric current, and Joules represent energy. Each of these units measures different electrical properties and does not directly relate to the measurement of resistance.
