Question about electrical components

    1. The problem statement, all variables and given/known data

    I had lab and I don't quite understand why I did what we did. We used an analog and digital VOM and used it to record the ohms and volts of various electrical components. I was wondering why when using the analog that different devices read completely different ohm readings. Take for example, our Buss fuse didn't even make the needle move, but the diode and the resistor made it go to infinite ohms. How do I figure out what they are supposed to read, and what to expect before going to lab. I couldn't find anything in my book or the lab manual. Also, I was wondering why a resistor would measure outside of its' tolerance range. Is this because it was faulty? Any help is appreciated.

    2. Relevant equations

    none

    3. The attempt at a solution

    Just need some explanation. I am not looking to solve anything, I am just confused on what we did.
