Walker, Halliday & Resnick β€” Current and Resistance: Problem 2

2 A wire 8.00 m long and 6.00 mm in diameter has a resistance of 30.0 m\(\Omega\). A potential difference of 23.0 V is applied between the ends. (a) What is the current in the wire? (b) What is the magnitude of the current density? (c) Calculate the resistivity of the wire material. (d) Using Table 26-1, identify the material.

πŸ“ Solution Approach

Given: 2 A, 8.00 m, 6.00 mm, 30.0 m, . A, 23.0 V

Find: (a) What is the current in the wire?; (b) What is the magnitude of the current density?; (c) Calculate the resistivity of the wire material

This problem covers key concepts in Current and Resistance from Principles of Physics 11th ISV Edition by Walker, Halliday & Resnick.
