What is resistance measured in?

Resistance is a measure of the opposition to the flow of electric current in a circuit. The unit of measurement for resistance is the ohm, named after the German physicist Georg Simon Ohm. When a material exhibits resistance, it impedes the movement of electrons, which is crucial to understanding how electrical circuits function. This concept is encapsulated in Ohm's Law, which states 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 of the conductor. This relationship is fundamental in both theoretical and practical aspects of electrical engineering and utility marketing, helping practitioners understand how to manage and predict electrical flows efficiently.
