Charge distribution and total charge

AI Thread Summary
To determine the charge distribution on two curved metal plates with a 9V potential, the charge distribution can be expressed as dQ/dA, and the total charge can be calculated by integrating this distribution over the entire surface area. It is suggested that to find the total charge, one might consider the charge distribution on a single plate and then double it, though this approach is questioned as all charge resides on the inner surfaces. The Schwarz transformation is referenced as a method for solving cylindrical capacitor problems, but the user is seeking alternative methods due to difficulty finding resources. Overall, clarity on the charge distribution and appropriate mathematical methods is needed for accurate capacitance calculations.

I am having two metal sheets which are curved and fitted on the outer sides of a pipe. A 9V pottential is applied to both the plates.
Dimensions of the plate = 130mm X 65mm (L X B)
How can i find the charge distribution on the plates to find the total charge. I need this to calculate the capacitance produced. ( mathematical way)

I have seen that the charge distribution on a surface = dQ/dA and total charge Q = intrgrating this charge distribution over the whole area.

So inorder to find the charge distribution over the whole surface, i need to add twice the charged distribution on a single plate. ( am I correct??)

Smythe "Static and Dynamic Electricity" 3rd Edition Chapter IV uses the Schwarz transformation to solve cylindrical geometry capacitor problems.

Why do you think you have to multiply the charge by two? All of the charge is on the inside surfaces.

Hey bob

I looked for schwarz transformation to calculate that in google. but could find anything. Is there any other method.
 
Thread 'Motional EMF in Faraday disc, co-rotating magnet axial mean flux'
So here is the motional EMF formula. Now I understand the standard Faraday paradox that an axis symmetric field source (like a speaker motor ring magnet) has a magnetic field that is frame invariant under rotation around axis of symmetry. The field is static whether you rotate the magnet or not. So far so good. What puzzles me is this , there is a term average magnetic flux or "azimuthal mean" , this term describes the average magnetic field through the area swept by the rotating Faraday...
