Firstly I have to admit this is a homework question, but I am really confused about it.
Problem : "5. You have found that all components have 0V across it and the power supply has the correct voltage. What are you looking for as a problem?"
Now there are three possible answers:
A. Bad power supply
B. Open component
C. Shorted component
However, if the the power supply has the correct voltage, and there are zero volts across each component then there isn't an open component. One component must have the source voltage across it.
If there was a short then all the components would have zero volts, but also the power supply would have a lower voltage?
"Power supply has the correct voltage", does that mean that there is a supply to the PSU, or does it mean that the PSU has the correct output voltage?

I think you're right, Jim. Electroliite, check your question, which no doubt you've quoted incorrectly:
Problem : "5. You have found that all components have 0V across it and the power supply has the correct voltage. What are you looking for as a problem?"
For proper grammar, that should be "...all components have 0V across them..."
And you've asked:
However, if the the power supply has the correct voltage, and there are zero volts across each component then there isn't an open component. One component must have the source voltage across it.
Sorry, I didn't mean to jump on you for being the one at fault. I think you have a case for taking issue with the wording of the question, although I'd try to be tactful in bringing it up with your professor (or whoever wrote the exam), should you choose to. The lack of attention to detail in literature by people who are otherwise leaders in their fields is a constant source of bemusement (and amusement) for me. Still, there are none of us who are not infallible.
