Question

A 14 gauge copper wire of diameter 1.628 mm carries a current of 12.5 mA. (a) What is the potential difference across a 2.00 m length of the wire? (b) What would the potential difference in part (a) be if the wire were silver instead of copper, but all else were the same?

Step 1

68 x 10^-8 Ωm. The length of the wire is 2.00 m. The cross-sectional area of a 14 gauge wire can be found using the formula: Area = π x (diameter/2)^2 The diameter of the wire is 1.628 mm, which is equal to 0.001628 m. Plugging in the values, we get: Area = π Show more…
