일반물리학 2 — Current and Resistance: Problem 3

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