## Homework Statement

A capacitor of capacitance 10 uF is raised to a potential difference of 150V. After disconnecting from the battery, it is connected to a capacitor of capacitance 5 uF. Find the energy of the system.

## Homework Equations

Energy supposed to be equal in the first case and second case right? But the solution showed that the energy is decreased as the capacitor is connected with uncharged one. Which one is right?

## The Attempt at a Solution

Solution for first assumption: 0.1125 J.

Solution for the second: 0.075 J.
