Drop Lifetime given Diffusion Current Formula

What do you mean by residual current and diffusion current in polarography ?

The current that flows in the absence of the depolarizer (i.e. due to the supporting
electrolyte) is called residual current. This has to be taken into consideration while
interpreting the polarograms.
It is the sum of the relatively larger condenser current (ic) and a very small faradic
current (if).
Migration Current is due to migration of cations from the bulk of the solution
towards cathode due to diffusive force, irrespective of concentration
gradient.
