1. The problem statement, all variables and given/known data A cylindrical capacitor(2 round plates with dielectric between them) with radius a, height hc and volume V. A sinusoidal voltage V0 is applied to the capacitor plates. Find the E-field inside the cap, Mag field Hs on the cap side wall(i.e at r=a) Use poynting theorem over the cylindrical surface to find power P provided to the cap. determine complex impedance Z of the cap, using the result of above. (ignore fringe fields) (crude fig. attached) 2. Relevant equations 3. The attempt at a solution I found the E field, which is (sigma/epsilon) H field at a is I/2(pi)a (using ampere's law) poynting theorem ExH, gave me (sigma/epsilon)*(I*hc) I have no idea how to get cap impedance from ExH result.
