WebSep 12, 2024 · Thus, we obtain the following form of Poisson’s Equation: (5.15.1) ∇ 2 V = − ρ v ϵ. Poisson’s Equation (Equation 5.15.1) states that the Laplacian of the electric potential field is equal to the volume charge density divided by the permittivity, with a change of sign. Note that Poisson’s Equation is a partial differential equation ... A level surface, or isosurface, is the set of all points where some function has a given value. If f is differentiable, then the dot product (∇f )x ⋅ v of the gradient at a point x with a vector v gives the directional derivative of f at x in the direction v. It follows that in this case the gradient of f is orthogonal to the level sets of f. For example, a level surface in three-dimensional space is defined by an equation of the form F(x, y, z) = c. The gradient of F is then normal to the surface.
