Ohmic resistance, also known as electrical resistance, is a measure of the opposition of a material to the flow of electric current through it. There are different synonyms for Ohmic resistance that are commonly used in various contexts. Some of the most commonly used synonyms include electrical resistivity, impedance, conductivity, resistance, and reactance. These terms are used to describe the different types of resistance present in electrical circuits. Electrical resistivity describes the resistance of a material to the flow of electric current, while impedance refers to the total opposition of an electrical circuit to the flow of current. Conductivity refers to the ability of a material to conduct electricity, and reactance describes the opposition of an electrical circuit to the flow of alternating current.
