IMPORTANT
Consider two conducting spheres of radii R1and R2 with R1>R2, separated by large distance. If the two are at the same potential, the larger sphere has more charge than the smaller sphere, then, the charge density of the smaller sphere is more than that of the larger one.

A test charge q is made to move in the electric field of a point charge Q along two different closed paths (see figure). First path has sections along and perpendicular to lines of electric field. Second path is a rectangular loop of the same area as the first loop. The work done in the first path is more than that of the second path.
