WebAnswer (1 of 6): Resistivity is a measure of the resistance of a given size of a specific material to electrical conduction. Although materials resist the flow of electrical current, … The ohm (symbol: Ω) is the unit of electrical resistance in the International System of Units (SI). It is named after German physicist Georg Simon Ohm. Various empirically derived standard units for electrical resistance were developed in connection with early telegraphy practice, and the British Association for the … See more The ohm is defined as an electrical resistance between two points of a conductor when a constant potential difference of one volt, applied to these points, produces in the conductor a current of one See more The siemens (symbol: S) is the SI derived unit of electric conductance and admittance, historically known as the mho (ohm spelled backwards, symbol … See more The rapid rise of electrotechnology in the last half of the 19th century created a demand for a rational, coherent, consistent, and international system of units for electrical … See more The symbol Ω was suggested, because of the similar sound of ohm and omega, by William Henry Preece in 1867. In documents printed before WWII the unit symbol often consisted of the raised lowercase omega (ω), such that 56 Ω was written as 56 . See more The power dissipated by a resistor may be calculated from its resistance, and the voltage or current involved.
