WebJun 21, 2024 · The total energy stored in the electrostatic field is obtained as an integral of W E over all space. This total energy, U E, can be expressed in terms of the potentials and charges on the electrodes that created the electric field. This can be shown by starting from the vector identity. where is any vector field and V is a scalar function. WebNov 14, 2014 · Homework Equations. The field on the axis of a charged disk: I don't think that's right! Think of the disc as an infinite number of infinitely small annuli ranging in radius from 0 to R. where R = radius of disc. You probably have the formula for the E field along the axis for a ring (thin annulus) somewhere. Extra thought: what is the E field ... jonathan hron
