Four 4*μF* capacitors are connected into a square. A battery of unknown voltage is connected between the diagonal corners of the square. As a result, one of the 4*μF *capacitor is charged to 0.12*μC*.

a) Draw the schematic of the connection.

b) How much energy is stored in this 4 *μF *capacitor?

c) Find the total amount of charge provided by the battery.

d) Find the voltage of the battery.
