* Given: Length of wire (L) = 50 m Cross-sectional area (A) = 0.13 cm^2 Material = Copper * Resistivity of copper (ρ) = 1.7241 x 10^-8 Ω-m * Using the formula: R = ρL/A * Substitute the values: R = (1.7241 x 10^-8 Ω-m) x (50 m) / (0.13 cm^2) R = 1.3252 x 10^-6 Ω R = 1.3 Ω Therefore, the resistance of the copper wire is 1.3 Ω.
