Homework Help: Parallel plate capacitor

  1. Apr 27, 2010 #1
    We have got a parallel plate capacitor . The distance between the plates is 2*h and each plate's dimensions are a,b . Between the plates there exists dielectric e1 in the volume 0<z<h and e2 in the volume h<z<2*h (out of the plates e0 ) , with e1,e2>>e0 . At z=h we place another plate with dimensions l,b (l<a) like the figure . The potential of the plates at z=0 , z=h is 0 and at z=2*h is V . What is the capacity of the whole system?




    figure :
    ____ z=2*h
    e1
    __ z=h e0
    e2
    ____ z=0
