WebFields have two measures: a field force and a field flux. The field force is the amount of “push” that a field exerts over a certain distance. The field flux is the total quantity, or effect, of the field through space. Field force and flux are roughly analogous to voltage (“push”) and current (flow) through a conductor, respectively ... WebVoltage from Electric Field. The change in voltage is defined as the work done per unit charge, so it can be in general calculated from the electric field by calculating the work done against the electric field. The work per unit charge done by the electric field along an infinitesmal path length ds is given by the scalar product.
