🤓 Based on our data, we think this question is relevant for Professor Halihan's class at OKSTATE.
radius = 1.63 mm
mass of 24.1 kg
resistance = 2.061 ohm per km (Ω/km)
d (copper) = 8.96 g/cm3
Calculate the volume of the copper wire:
V = 2689.7321 cm3
Convert radius from mm to cm:
r = 0.163 cm
Calculate the height (length) copper (assuming it is a cylinder):
A length of #8 copper wire (radius = 1.63 mm) has a mass of 24.1 kg and a resistance of 2.061 ohm per km (Ω/km). What is the overall resistance of the wire? (d (copper) = 8.96 g/cm3)
