WebAccording to AllAboutCircuits.com, electrical resistance, measured in Ohms, is essentially electrical friction encountered by electrons as they move through a conductor. Ohms are typically symbolized by the Greek letter omega. The easiest way to measure resistance in a circuit is to use an ohmmeter or a multimeter. WebElectrical resistance is measured by either of two methods: constant current or constant voltage. The constant current technique sources a known current through an unknown resistance and the resulting voltage is measured. This technique is generally used for resistance values below 200M ohms.
