Electrical resistance of a wire with a circular cross-section of a diameter of 0.5 mm is 2 Ω. The length of the wire is 8 m. How long should be a wire of the same material but with the radius twice as big, so that the resistance of the wire is also 2 Ω? Determine the resistivity of the material, of which the wire has been made. house flipper - luxury dlc
