In summary, the conversation discusses the differences between electric potential energy, potential difference, and electric potential in layman's terms. It is explained that potential energy and potential difference are relative quantities, while electric field and electric potential are properties of a ...
Determine electric potential energy given potential difference and amount of charge. Figure 1. A charge accelerated by an electric field is analogous to a mass going down a hill. In both cases potential energy is converted to another form. Work is done by a force, but since this force is ...

As a result, we can write “Electric field is the negative space derivative of electric potential” as the relationship between electric field and electric potential. Hence, the electric potential is per unit charge at a location in a static electric field, whereas the electric field or electric...
What is the difference between Electric Potential and Potential Energy? Electrical Potential: It is the amount of work done on a charge to move it from a reference point to a specific point. {eq}V = \dfrac {kq}{r} {/eq} Wherekis coulomb's constant.qis the magnitude of the cha...
