Question:
A transmission-line cable with a length of \(2 \mathrm{~km}\) consists of 19 strands of identical copper conductors, each \(1.5 \mathrm{~mm}\) in diameter. Because of the twist of the strands, the actual length of each conductor is increased by \(5 \%\). Determine the resistance of the cable if the resistivity of copper is \(1.72 \mu \Omega\)-cm at \(20^{\circ} \mathrm{C}\).
