Fig.1 shows a cylindrical conductor exposed to an external electricfield which approaches at infinity. The associated boundary
condition at infinity becomes . Properfunctional form of the potential is chosen as of which both terms are solutions to the Laplace' equation. Since the potentialon the conductor surface is , we have .
