Homework Statement

Homework Equations

The Attempt at a Solution

Assuming the current is steady,
I = JA, where J is the current density and A is the cross- sectional area
$E = J/\sigma$
Can I take $\sigma$ uniform here ?

 

[efdee]

What is needed for an electrical current?
All conditions fulfilled?
How about your assumption?

The sigma can be taken uniform here.

Assuming the current is steady

Which current? Are you assuming that the capacitor is charging?

 

[Pushoam]

Which current? Are you assuming that the capacitor is charging?

Current in the loop.
Is the other end touching the capacitor?

 

[Pushoam]

The sigma can be taken uniform here.

Then, the potential difference across the resistance will be V = Eh
So, current I = Eh/R , but this creates perpetual motion machine which is wrong.

Suppose you took any piece of conducting material and suddenly placed it between the plates of a charged capacitor. Would you get any current in the material? If so, would the current last very long? Why or why not?

 

[efdee]

It is not very clear. However I believe
there is no current at all !

that is incorrect

why would you say that ?
