Two identical capacitors of 12 pF each are connected in series across a 50 V battery. Calculate the electrostatic energy stored in the combination. If these were connected in parallel across the same battery, find out the value of the energy stored in this combination.
The energy stored in capacitor, when connected in series combination;
We have given,
Hence, the energy stored in capacitor ;-
(Given; V=50)
Now, when capacitors are connected in parallel,
the value of the capacitor is given as,
there, energy in the capacitor in parallel combination is given as ;
