Resistance wire - Wikipedia

Resistance wire is wire intended for making electrical resistors (which are used to control the amount of current in a circuit). It is better if the alloy used has a high resistivity, since a shorter wire can then be used. In many situations, the stability of the resistor is of primary importance, and thus the alloy's temperature coefficient of resistivity and corrosion resistance play a large part in material selection.

職業: Chemistry Expert預估閱讀時間: 2 分鐘其他人也問了以下問題What is the electrical resistivity of aluminium?Heat of Vap. Electrical resistivity of Aluminium is 26.5 nΩ·m. Electrical resistivity and its converse, electrical conductivity, is a fundamental property of a material that quantifies how strongly it resists or conducts the flow of electric current. A low resistivity indicates a material that readily allows the flow of electric current.

Aluminium – Electrical Resistivity and Electrical Conductivity

www.periodic-table.org/Aluminium-electrical-resistivity/What is the resistivity of a copper wire?For example, the electrical conductivity of copper is σ ≈ 5.95 × 10^7 S / m, and the electrical resistivity of copper is ρ ≈ 1.68 × 10^ (-8) Ω × m. How do I calculate the resistance of a wire? Find out the resistivity of the material the wire is made of at the desired temperature. Determine the wire's length and cross-sectional area.
