How can you measure low resistance accurately?

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. The ampere is named for French physicist and mathematician André-Marie Ampère (1775–1836), who studied electromagnetism and laid the foundation of electrodynamics. In recognition of Ampère's contributions to the creation of modern electrical science, an international convention, signed at the 1881 International Exposition of Electricity, established the ampere as a standard unit of electrical measurement for electric current. meme seattleWebconnected in series is the sum of the individual resistances of the resistors.
