Homework Help: Current In Coil Around A Capacitor

  1. Oct 27, 2009 #1
    1. The problem statement, all variables and given/known data

    See attachment.

    2. Haven't gotten there yet.


    The problem I'm having with this is seeing the connection between the capacitor (at least, that's what I assume that square thing is) and the loop. Frankly, I don't see why there would be or why there must be current in the loop at all. These are thought processes I've followed so far:

    1. Energy stored in the capacitor implies there's a charge on the capacitor.

    2. Charge on the capacitor implies that there is a voltage difference across the capacitor.

    3. Voltage across capacitor causes a current in the loop...?


    1. Charged up capacitor means the current in the capacitor has stopped/is stopping.

    2. Dwindling current implies a changing electric field.

    3. Changing electric field induces a magnetic field in loop.

    4. ???? somehow that relates to current in the loop?

    It will take a day for your attachment to be approved. It would be better to upload the diagram to a free photo site like photobucket.com, then post a link to it here. If you put IMG before the link and /IMG after (both in square brackets), the diagram will appear right in the post.
