Dimensional formula for product of charge per unit volume and voltage
The number of particles crossing the unit area perpendicular to the x –axis per unit time, is given by:
N=−D(n2−n1x2−x1)
Where
n1 and n2
are the numbers of particles per unit volume for the values of x meant to be x1 and x2 respectively. What is the dimensional formula for the diffusion constant D?
