Question

Fully charged parallel plate capacitor is connected across and answers identical capacitors show that the energy stored in the combination is less than stored initially in the sindhi capacitor

Answer 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.


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
