#1

A fully charged parallel plate capacitor is connected across an uncharged identical capacitor. Show that the energy stored in the combination is less than Stored initially in the single capacitor.


#2

Initially, if we consider a charged capacitor, then its charge would be

Q = CV

Then, this charged capacitor is connected to uncharged capacitor.
Let the common potential be${ V }_{ 1 }$. The charge flows from first capacitor to the other capacitor unless both the capacitors attain common potential
