Charge distribution and total charge

  1. Nov 19, 2009 #1
    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.
