19.1 Electric Potential Energy: Potential Difference
Potential energy accounts for work done by a conservative force and gives added insight regarding energy and energy transformation without the necessity of dealing with the force directly. It is much more common, for example, to use the concept of voltage (related to electric potential energy) than to deal with the Coulomb force directly.

Difference between voltage and potential energy in a capacitor
$begingroup$ A charge placed in the capacitor will have potential energy, but that is separate from the potential energy stored in the capacitor. If that''s what you were asking. Also, there was a typo in the result of the integral (as you would notice if you did it yourself ;-p) - I fixed it now.
Solution Set
For the -q and + Q system, the potential energy U = -kqQ/r which remains constant if the distance r of separation of the two charges remains constant. The electric force does no work because the force is always perpendicular to the displacement of the negative charge when it moves in a circular path around the positive charge. Thus, there is no potential energy …

Then you will have changed the potential energy of the test charge from zero to (q_{T}varphi). To do that, you have to do an amount of work (q_{T}varphi) on the test charge. We''re assuming that the test charge was initially at rest and is finally at rest. You have to push the charge onto the sphere. You apply a force over a distance to give that particle the potential energy (q_{T ...
