What is the unit of measure for electrical resistance?

The unit of measure for electrical resistance is the ohm. This unit is symbolized by the Greek letter omega (Ω) and is defined as the resistance between two points of a conductor when a constant potential difference of one volt, applied between those points, produces a current of one ampere. The concept of electrical resistance is central to understanding how electrical circuits function, as it describes how much a material opposes the flow of electric current. Recognizing the correct unit of resistance is essential for electrical engineering and enhancing one’s comprehension of Ohm’s Law, which relates voltage, current, and resistance in a circuit.
