A charge is placed on a speherical conductor of radius r1. this sphere is then connected to a distant sphere of radius r2 (not equal to r1) by a conducting wire. after the charges on the spheres are in equilibrium... is it reasonable to say that both spheres are at the same potential? regardless of the different radii C=Q/V so i think the amount of charge distributed on both speheres will differ but the potential will still be the same since the spheres are in equilibrium. i don't know i don't really understand the concept very well.
