Electric field energy formula
WebIn the case of the electric field, Equation 5.4 shows that the value of →E (both the magnitude and the direction) depends on where in space the point P is located, with →ri measured from the locations of the source charges qi. In addition, since the electric field is a vector quantity, the electric field is referred to as a vector field. WebThus, the formula of energy density will be the sum of the energy density of electric and magnetic fields both together. Solved Examples.
