Webb3 apr. 2024 · An ohmmeter is a device that measures the amount of electrical friction generated as electrons pass through an electrical conductor. Also known as electrical resistance, its value is expressed in units of “ ohm .” WebbIn SI, the unit for resistivity is Ω·m. An Ω·m is defined as a resistance of a conductor, which is 1 m long, has a cross-sectional area of 1 m² and resistance of 1 ohm. To make calculations simpler, it is common in electrical engineering to use the derivative of the value of resistivity, which is measured in Ohm·mm²/m.
