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 https://amgoman.com
