WebJan 16, 2024 · To calculate the copper wire weight per foot, simply enter 1 foot (or 0.3048 cm) into the "Length" field and let our calculator find the weight for you. For example, 1 foot of 0.46 in ( 1.168 cm) diameter round pure copper wire will weigh 0.645 lb (or 0.293 kg ). WebThe resistance of a conductor of length L and diameter d is given by R= π(d/2) 2ρL where ρ= resistivity of material of conductor. When diameter is doubled, the resistance becomes R= π(2d/2) 2ρL =R/4. Was this answer helpful? how to add googlefinance to excel

WebThe resistance R of a cylinder of length L and cross-sectional area A is [latex]R=\frac{\rho L}{A}\\[/latex], ... The diameter of 0-gauge copper wire is 8.252 mm. Find the resistance of a 1.00-km length of such wire used for … http://www.phys.ufl.edu/courses/phy2049/sum07/solutions_ex2.pdf WebAnswer (1 of 3): The resistance is proportional to the length of the wire and inversely proportional to its cross-sectional area. Half the diameter means one quarter of the area, so this increases the resistance by a factor of 4 (from 1 ÷ (1/4) ). Twice the length means twice the resistance, so t... how to add google fonts in angular
