Problem: 3
An electrical cable consists of 63 strands of fine wire, each having 2.65 µΩ resistance. The same potential difference is applied between the ends of all the strands and results in a total current of 0.750 A. (a) What is the current in each strand? (b) What is the applied potential difference? (c) What is the resistance of the cable?
