Question

What is the resistance (in Ω) of a 17.0 m long piece of 29 gauge copper wire having a 0.286 mm diameter?

Answer 1

Resistance is proportional the length and inversely proportional to the area, and the formula is

R = ρL/A where ρ is the resistivity and is temperature dependent.

Look up the resistivity of copper in ohm-meters, calculate the area in square meters. and plug in the values into the formula.
