Resistance of an aluminum cable with length 10 m and cross sectional area of 3 mm 2 can be calculated as. Temperature The resistivity of materials changes with temperature.

Electrical Resistivity Table for Common Materials Table of the electrical resistivity for materials that may be used in electrical and electronic components, including the resistivity of copper, resistivity of brass and the resistivity of aluminium. aluminium resistivity . Resistance formula is: R = ρL/A Where: ρ: Resistivity constant of the material, in Ω.m L: Length of the wire, in meter A: Cross sectional area of the wire, in m^2 R: Resistance, in ohms (Ω) resistivity of aluminium If you have any questions or good suggestions on our products and site, or if you want to know more information about our products, please write them and send to us, we will contact you within one business day. This article discusses the resistivity formula and its derivation. m. Combined with it's light weight and alloyed with some other metals to make it stronger, aluminum is ideal for electrical cables. R = (2.65 10-8 Ω m) (10 m) / ((3 mm 2) (10-6 m 2 /mm 2)) = 0.09 Ω.

Resistivity refers to the electrical resistance of a conductor of a particular unit cross-sectional area and unit length. It is commonly used to characterize materials made by semiconductor doping, metal deposition, resistive paste printing, and glass coating . Wire Resistance A one-meter long wire with a cross section of one square millimeter has a resistance of 1.7 milliohms (.0017 Ohm) if it is made of copper, and 2.5 milliohms if it is aluminum. The conductivity of copper is about 0.6 megamho/cm while that of aluminum is about 0.4 megamho/cm. resistivity of aluminium If you have any questions or good suggestions on our products and site, or if you want to know more information about our products, please write them and send to us, we will contact you within one business day.
