Webresistivity, electrical resistance of a conductor of unit cross-sectional area and unit length. A characteristic property of each material, resistivity is useful in comparing various … WebThe unit of the electrical resistance, measured with direct current, is the ohm (abbreviated Ω), named after the German physicist and mathematician Georg Simon Ohm (1789-1854). According to ohm’s law, the resistance R is the ratio of the voltage U across a conductor and the current I flowing through it: R = U / I. Hence it follows: 1 Ω = 1 V/A.
WebThe resistance of the resistor is R = ρ L A R = ρ L A. Figure 9.15 A model of a resistor as a uniform cylinder of length L and cross-sectional area A. Its resistance to the flow of … WebResistivity is the measure of the resistance that material provides per unit length and per unit cross-sectional area. Mathematical representation of resistance – ρ = RA/L. The SI unit of specific resistance is ohm-meter (Ωm). Superconductors have zero resistivity in the superconducting state, i.e. at very low temperatures.
