2. In the circuit below, the switch SW is initially disconnected. Suppose that the electric current in the circuit has reached equilibrium. Use the negative end of the battery as the zero potential reference point. a) b) C) d) Calculate the potential at point (a). Calculate the quantity of charge carried by each capacitor. (Note that the two capacitors are connected in series and thus always sharing the same charging current.) Calculate the potential at point (b). If the switch SW is connected, the potential at point (b) will be forced to equal the potential at point (a). Calculate the quantity of charge on each capacitor after the current in the circuit reaches equilibrium
