Compute each part of following question:
Question: Copper has a resistivity of 1.7 x 10-8 ohm/m.
Part A: What is the resistance of a 1 m long wire of radius 0.4 mm?
Part B: A cable is made by bundling together 100 such wires. What is the resistance per meter of such a cable?
I am need of complete solution for this question please help- me out to get right answer. Thanks.
