WebEnergy is the capability to do work or perform some action and can be thought of as something that is possessed or stored. It exists in several forms like light, heat, electrical, potential energy, or other forms. Work and energy have similar units and are closely related. Energy can be put in storage, but that cannot be done for work. Web12 sep. 2024 · The electron gains kinetic energy that is later converted into another form—light in the television tube, for example. (Note that in terms of energy, “downhill” for the electron is “uphill” for a positive charge.) Since energy is related to voltage by $\Delta U = q\Delta V$, we can think of the joule as a coulomb-volt.
