CHECK THE SOLUTION.
(a, c, d)
The charges stored in different capacitors before and after closing the switch S are:


The amount of charge flown through the battery is q = 20 µC
∴ Energy supplied by the battery is:
U = qV = (20 × 10 –6 ) × (30) J
= 0.6 mJ
Energy stored in all the capacitors before closing the switch S is:

Heat generated,

and charge flown through the switch is
