A wire 1.2 m long and 0.4 mm diameter has a resistance of 4.9. Calculate the resistance of another wire of the same material whose length is 0.8 m and diameter is 0.24 mm.© BrainMass Inc. brainmass.com September 26, 2022, 9:04 pm ad1c9bdddf
R = pL/A
where resistivity, p, is constant since it ...
This solution is provided in 54 words. It provides an equation for resistance to find resisitivity and then resistance of the second wire.
