a) An aluminum wire 7.5m long is connected in parallel with a copper wire 6m long. When a current of 5A is passed through the combination, it is found that the current in the aluminium wire is 3A. If the diameter of the aluminium wire is 1mm, determine the diameter of the copper wire. Assume the resistivity of copper to be 0.017µ0m and that of aluminium to be 0.028 µ0m.

You are working as an electrician in a large steel manufacturing plant, and you are in the process of doing preventive maintenance on a large DC generator. You have megged both the series and shunt field windings and found that each has over 10 M to ground. Your ohmmeter, however, indicates a resistance of 1.5 across terminals S1andS2. The ohmmeter indicates a resistance of 225 between terminals F1andF2. Are these readings normal for this type machine, or is there a likely problem? Explain your answer.
The wires of our appliances are insulated with a material mixed with rubber, which has a very high resistivity. If a certain wire has a length of 2.5 m and the outer diameter is 5mm and its inner diameter is 0.5mm, what is its resistance? Note that the inner diameter is present to leave a hallow place where conducting wire ( usually copper) is present. Follow the format: Given: Required: Equation: Solution: Answer:
