Current In Coil Around A Capacitor

AI Thread Summary
The discussion revolves around understanding the relationship between a capacitor and current in a loop. Key points include the notion that energy stored in a capacitor indicates a charge, which leads to a voltage difference across it. This voltage difference is thought to potentially cause current in the loop. Additionally, the idea is presented that a charged capacitor may lead to a diminishing current, resulting in a changing electric field that induces a magnetic field in the loop. The conversation emphasizes the need for visual aids to clarify these concepts, suggesting the use of image hosting for better communication.

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.
 
Thread 'Variable mass system : water sprayed into a moving container'
Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
