Nernst-Planck equation

The Nernst-Planck equation describes how charged particles, like ions, move in a solution. It takes into account two main factors: the concentration gradient, which is how particles spread out from areas of high concentration to low concentration, and the electric field, which influences their movement due to charge. Essentially, it helps us understand how ions drift towards areas with lower concentration and how they are affected by electric forces, combining diffusion and electromigration. This equation is crucial in fields like chemistry, biology, and materials science, especially in processes like nerve signal transmission and battery operation.
