A capacitor of capacity

C

is charged to a potential difference

V

and another capacitor of capacity

2 \mathrm{C}

is charged to a potential difference

4 \mathrm{~V}

. The charging batteries are disconnected and the two capacitors are connected with reverse polarity (i.e. positive plate of first capacitor is connected to negative plate of second capacitor). The heat produced during the redistribution of charge between the capacitors will be

View answer and explanation

Correct option: D

\frac{25 C V^2}{3}

Option D (

\frac{{25 C V^2}}{{3}}

) is correct because it represents the heat produced during charge redistribution, calculated using the difference in initial and final energies.
