Radial flow of charge across cylinder?

AI Thread Summary
In a system with two concentric cylinders, where the outer cylinder is hollow and the inner one is solid, and the space between them is filled with a high-resistivity material, charge will flow from the inner cylinder to the outer cylinder when a voltage V is applied. The electric field can be calculated using Gauss' Law, which is applicable despite the resistive medium, as it helps determine the charge distribution. The symmetry of the system suggests a uniform electric field in the radial direction. The resistivity of the material and the dimensions of the cylinders will influence the rate of charge flow. Understanding these principles is essential for analyzing the behavior of the charge in this configuration.

Hi

Please help me understand how charge flows in this case:

There are 2 concentric cylinders, the outer one is hollow but the inner one is solid. The space between them is filled with a material of high resistivity. Now an electric circuit with voltage V is connected to the cylinder's faces. +ve end of the circuit goes into the outer cylinder and -ve end to the inner cylinder. The cylinders themselves have negligible resistance. What will happen in terms of charge flow here?

Is there any symmetry? Use Gauss law to calculate the electric field.
 
I tried using Gauss' Law, but I think there is charge flow from inner to outer cylinder through the resistive medium and Gauss' Law won't work in that case.

I am only given the voltage V of the battery, the resistivity of the in-between material \rho, the inner radius r1, outer radius r2, and the length L of the 2 cylinders.
 
Thread 'Inducing EMF Through a Coil: Understanding Flux'
Thank you for reading my post. I can understand why a change in magnetic flux through a conducting surface would induce an emf, but how does this work when inducing an emf through a coil? How does the flux through the empty space between the wires have an effect on the electrons in the wire itself? In the image below is a coil with a magnetic field going through the space between the wires but not necessarily through the wires themselves. Thank you.

I am reading the Griffith, Electrodynamics book, 4th edition, Example 4.8. I want to understand some issues more correctly. It's a little bit difficult to understand now. > Example 4.8. Suppose the entire region below the plane ##z=0## in Fig. 4.28 is filled with uniform linear dielectric material of susceptibility ##\chi_e##. Calculate the force on a point charge ##q## situated a distance ##d## above the origin. In the page 196, in the first paragraph, the author argues as follows ...
