By this point in the class, you are undoubtedly familiar with the concept of resistance and the role it plays in electrical circuits. This week in lab, we will need to better understand resistivity, the property of a material that, along with its geometry, determines its resistance. (a) Typically in the lab we use copper wires as the connecting wires of our circuits. Copper has a resistivity of c = 1.68 108 m and the wires used in the lab have a length of 30 cm and a diameter of 1.024 mm. What is the resistance of one of these wires? Rc = m (milli-Ohms) (b) Now consider a nichrome wire similar to what you will use in this week's lab. Nichrome has a resistivity of n = 100 108 m. What is the resistance of a nichrome wire with the same length and diameter as the copper wires typically used in the lab? Rn = m (milli-Ohms) (c) Compare the resistances you calculated in parts (a) and (b) to the values of resistors you have used in the lab to this point. Is it reasonable that we have often neglected the resistance of copper wires? Would it
