Part 1 Before we can consider the effects it might have, we must consider the high tension power line itself. Such wires are frequently constructed by twisting aluminum or copper wires together into a large flexible bundle. Consider such a copper cable with a diameter of 4 cm. If this cable is 10 km long, what is its resistance? Remember: Resistance = Resistivity * Length / Area Resistivity of copper is 0.0000000168 Ω-m Cross sectional Area of...

View Policies Show Attempt History An aluminum transmission line with a diameter of 20 mm has an electrical resistance of Relec' = 2.636 x 109/m and carries a current of 700 A. The line is subjected to frequent and severe cross winds, increasing the probability of contact between adjacent lines, thereby causing sparks and creating a potential fire hazard for nearby vegetation. The remedy is to insulate the line, but with the adverse effect of increasing the conductor operating temperature....
