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.

Using superstition, find the value of i0 if voltage source at the left is 10, angle - 30 degrees V, and current source is 2, angle zero degrees. A total of three sources will be considered, separately. The 24 volt source is DC. When this source is acting alone, the capacitor will be open-circuited.
An ideal battery of terminal voltage 22 volts charges two practical batteries connected in parallel to each other. The parallel connection of the said practical batteries is connected across the ideal battery. The two practical batteries have the following specifications: 10 volts, 0.2 ohm; 8 volts, 0.5 ohm. Determine the total current being delivered by the source.
