Four capacitors are connected as shown below in the figure. Here C1 = 2 μF, C2 = 3 μF, C3 = 4 μF and C4 = 5 μF.

In the given circuit diagram, if a 4 Volt battery is connected between points A and B, what is the total charge stored on the capacitors ?

13 μC

2 microfarad is in parallel with the series combination of the other three.

Q = C V = 13.12 microfarads
