    Find the dimension of capacitor given [phi]E and Id

    ΔQ/Δt = CV/Δt = εAE/Δt = Id Thanks for the reply, still not sure how to solve this. Even with respect to time I can't see how the formulas can be setup to find the plate dimensions (A) without having d, or E. :confused:

    Find the dimension of capacitor given [phi]E and Id

    Could you elaborate? I don't see how that helps to solve for A or E

    Find the dimension of capacitor given [phi]E and Id

    Homework Statement The electric field between two circular plates of a capacitor is changing at a rate of 1.5x10^6 V/m/s (ΦE). If displacement current at this instant is Id=0.80x10^-8A, find the dimensions of the plates. Homework Equations Id=ΔQ/Δt=εΔΦE/Δt Q=CV=(εA/d)(Ed) Q=εAE...
