Solve the all parts of given question:
Question: A material is formed into a long rod with a square cross-section 0.50 cm on each side. When a 60V voltage is applied across a 20-m length of the rod, a 5.0A current is carried.
Part A: What is the resistivity of the material?
Part B: Is the material a conductor, an insulator, or a semiconductor?
Please show all work and steps to find the resistivity of the material.
