Current In Coil Around A Capacitor

Click For Summary
SUMMARY

The discussion centers on understanding the relationship between a charged capacitor and the current in an electrical loop. Participants explore the implications of energy storage in the capacitor, voltage differences, and the resulting current flow. Key points include the notion that a charged capacitor leads to a voltage difference, which can induce current in the loop, and that a diminishing current indicates a changing electric field, which in turn induces a magnetic field. The conversation emphasizes the need for visual aids to clarify these concepts.

PREREQUISITES
  • Basic understanding of capacitors and their function in circuits
  • Familiarity with electric fields and magnetic fields

1. Homework Statement

See attachment.

2. Haven't gotten there yet.



3.

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...?

OR

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.
