In physics, chemistry and biology, a potential gradient is the local rate of change of the potential with respect to displacement, i.e. spatial derivative, or gradient. This quantity frequently occurs in equations of physical processes because it leads to some form of flux . Definition One dimension


Activating function (AF, gradient of the electric field) of the

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 \(V({\bf r})\).

As shown in Figure 7.5.1, if we treat the distance Δs as very small so that the electric field is essentially constant over it, we find that. Es = − dV ds. Therefore, the electric field components in the Cartesian directions are given by. Ex = − ∂V ∂x, Ey = − ∂V ∂y, Ez = − ∂V ∂z. This allows us to define the "grad" or.


Electric Potential Electric Field as Potential Gradient

The electric field is said to be the gradient (as in grade or slope) of the electric potential. For continually changing potentials, Δ V Δ V and Δ s Δ s become infinitesimals and differential calculus must be employed to determine the electric field.
