Two dimensional potential mapping-Monte Carlo simulation

A very useful experiment of two dimensional potential mapping, namely electrolytic tank model, for graduate and post graduate level physics students is given here. Laplace's equation is solved for the above and the results are compared with the experiment. The agreement is so good that this is extended to complex problems. Monte Carlo simulation, an alternative to the above experiment, is developed for these complex problems and compared with the experimental results of electrolytic tank model.
