Diffusion-limited current planar and spherical electrodes

3 Diffusion-limited current planar and spherical electrodes 

The experiment leading to the diffusion-limited current involves application of a potential step at = 0 to an electrode, in a solution containing 

The mathematical solution to this problem is facilitated by using a dimensionless concentration 

The general solution to this equation is well known  

Since the second term of the right-hand side does not satisfy the second boundary condition (jt— oo, y- 0), then B (s) = 0. The third boundary condition in Laplace space is
