Solve the following problems given below:
Problem I: Calculate the resistance in Ohms of a 1.00 m long piece of Nichrome wire. Assume its diameter is 0.426 mm.
Problem II: Calculate the resistivity (SI units) of the material used to make a 933 Ohm resistor which has a length of 0.61 cm and a diameter of 1.3 mm.
Problem III: Using copper leads (wires) to connect different devices and multi meters to assemble various circuits, Calculate the resistance in Ohms of a typical lead, which would have a length of 36.8 cm and a diameter of 1.74 mm.
Please provide clear step by step solution with notes on concepts and equations being used.
