Consider the hypothetical situation. In a circuit with a capacitor and an ideal cell, potential difference across the capacitor would be the potential difference maintained by the cell. If the ideal cell is removed leaving the only the capacitor in the circuit without any resistance in the circuit, the capacitor would become discharged and finally charge on capacitor would be 0 and thus potential difference would be 0. Now since Capacitance=charge/potential difference, the capacitance would be 0/0? Am i right? Or if the cell is real charge would only approach 0 and hence potential difference too would approach 0 and hence C approaches 0/0? Is this correct?
