A dc power distribution cable has two #6 copper wires. The copper wire table in the textbook lists each wire as having resistance of Ro=.4028 ohms per thousand feet at temperature of 25C. The temperature coefficient of copper is alpha=.004 per C. IF the cable is expected to operate at 75C, then the resistance would be R = Ro +Ro(alpha)(delta*T), where delta*T=50C is the temperature rise above 25C. If the cable is 455 feet long, calculate the resistance of each wire at 75C. Calculate the total cable resistance due to both wires.
