The board is cut into a trapezoidal shape and is made of plastic. On the back of the board there is conductive paint shown here in green. On the front there are some resistors and capacitors, in addition to terminals for inserting the leads from a DC power supply. The legs of the resistors and capacitors go through the holes on the board and are soldered to the conducting paint on the back side. You also have a multi-meter which you can use as an ammeter or a voltmeter. 16 v 4700 16 10 8 O- 7 3. 6. 4 O+

- 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.14.
