    Click here????to get an answer to your question ️ A power cable of copper is just stretched (initial tension zero) straight between two fixed towers. If the temperature decreases, the cable tends to contract. The amount of contraction for a free copper cable of rod is 0.0002% per degree Celsius. A temperature decrease in C) of 10X will cause the cable to snap.

    2012-5-23u2002·u200238. Suppose instead of using a 12-gauge (diameter = 2.05 mm) solid copper cable you made a hollow copper cable of outer diameter 2.59 mm (10-gauge) and inner diameter 1.29 mm (16-gauge). Calculate the length of hollow cable that would give the same resistance as 1 m of 12-gauge solid cable. Use ρ(Cu) = 1.7 x 10 –8 Ω /m.
