Use the following schematic for questions 1, 2 and 3.


 Between which points would you expect to measure no voltage?
 Between which points would you expect to measure source voltage?
 The light bulb stops working. Using your meter, you read zero volts between points F and H and between E and J. You measure source voltage from I and B and from G and J. Where is the problem located?
