Identical metal plates are located in air at equal distance d from one another. The area of each plate is equal to A. Evaluate the capacitance of the system between P and Q if the plates are interconnected as shown in figure.

Figure shows a capacitive circuit with a switch Sw. a. What is the potential difference between a and b when the switch is open?
