• We can assign a capacitance to a single isolated spherical conductor of radius R by assuming that the “missing plate” is a conducting sphere of infinite radius.
• The field lines that leave the surface of a positively charged isolated conductor must end somewhere;
• the walls of the room in which the conductor is housed can serve effectively as our sphere of infinite radius.
• To find the capacitance of the conductor, we first rewrite the capacitance as:
• Now letting b→∞, and substituting R for a,
