Nernst-Planck equation



 The introduction to this article provides insufficient context for those unfamiliar with the subject.
Please help improve the article with a good introductory style.

The Nernst-Planck equation describes the flux of ions through a diffusive membrane under the influence of both an ionic concentration gradient (X) and electric potential (V).

It is defined :

\Phi = -D \nabla X - P X \nabla V

Where D is a set of constants related to scaling the concentration gradient (X) and P is a set of constants related to scaling the potential (V) across the diffusive membrane.
