We use the letter U to denote electric potential energy, which has units of joules (J). When a conservative force does negative work, the system gains potential energy. When a conservative force does positive work, the system loses potential energy, ΔU = − W.

Electric potential energy is a potential energy (measured in joules) that results from conservative Coulomb forces and is associated with the configuration of a particular set of point charges within a defined system.
4 Ιουλ 2022 · Electrical Potential Energy Formula. The electric potential energy is a scalar quantity. It is not a vector, although the electric field responsible for it is a vector. The magnitude depends upon two factors: The magnitude of the charges. Distance between the two charges.
Electric Potential \(V\) of a Point Charge. The electric potential \(V\) of a point charge is given by \[\underbrace{V = \dfrac{kq}{r}}_{\text{point charge}} \label{PointCharge}\] where \(k\) is a constant equal to \(9.0 \times 10^9 \, N \cdot m^2/C^2\).
21 Οκτ 2024 · Describe the relationship between electric potential and electrical potential energy. Explain electron volt and its usage in submicroscopic process. When a free positive charge \(q\) is accelerated by an electric field, such as shown in Figure \(\PageIndex{1}\), it is given kinetic energy.
Define electric potential energy. Apply work and potential energy in systems with electric charges. When a free positive charge q is accelerated by an electric field, it is given kinetic energy (Figure 7.2).
In short, an electric potential is the electric potential energy per unit charge. This value can be calculated in either a static (time-invariant) or a dynamic (time-varying) electric field at a specific time with the unit joules per coulomb (J⋅C −1 ) or volt (V).
