Work-energy theorem giving no work done on capacitor and dielectric when dielectric removed from capacitor [closed]
For this problem,
Do you please know why when considering that the capacitor and dielectric is our system, the work energy theorem gives the wrong sign for the change in electrostatic potential ...

Energy stored in a capacitor vs Work that the battery does [duplicate]
Say we have a battery at a fixed voltage of $V$ charging a capacitor with capacitance $C$.
When the capacitor is fully charged, the energy stored in it will be $\frac{1}{2}QV$, where $V$ is the final ...

What is the work done by battery and what does work done on battery mean?
Suppose we have a charged capacitor connected to a battery. Now we push the plates of the capacitor away from each other decreasing capacitance and hence energy stored in the capacitor decreases. Now ...
