How Do You Calculate The Resistance Of Copper Wire? Engineers often ask how to calculate the resistance of a cable, there is a very simple formula that works well within an ohm or so with copper cable. 19 ÷ by 2.5mm2 will give you 7.6 ohms per km. ÷ by 1000 for resistance per meter.
What Factors Affect Resistivity? What factors affect resistivity? The resistivity of the materials depends on a few factors, which are temperature, mechanical stressing, age hardening, and alloying. What are the 4 factors that affect resistance? The type of material of which the resistor is made. The length of the resistor. The thickness of the resistor.
What Factors Are Effect On The Resistivity? What factors are effect on the resistivity? The resistivity of the materials depends on a few factors, which are temperature, mechanical stressing, age hardening, and alloying. What factors affect resistivity? The factors like temperature, alloying, cold work, age hardening & mechanical stress affect the resistivity of electrical materials.
