WebSep 12, 2024 · The gradient of a scalar field is a vector that points in the direction in which the field is most rapidly increasing, with the scalar part equal to the rate of change. A particularly important application of the gradient is that it relates the electric field intensity \({\bf E}({\bf r})\) to the electric potential field \(V({\bf r})\). WebThe electric potential is the electric potential energy of a test charge divided by its charge for every location in space. Because it's derived from an energy, it's a scalar field. These two fields are related. The electric field and electric potential are related by displacement. Field times displacement is potential….
