An aluminum wire 7.5 m long is connected in parallel with a copper wire 6 m long. When a current of 5 A is passed through the combination it is found that the current in aluminum wire is 3 A. The diameter of aluminum wire is 1 mm. Determine the diameter of the copper wire. Resistivity of copper is 1.7 x 10 “ ohm-cm and that of aluminum is 1.724 micro-ohm-cm.

An ac resistance is higher than a dc resistance. True False
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.
