Jul 23, 2025 · We briefly defined a field for gravity, but gravity is always attractive, whereas the electric force can be either attractive or repulsive.

Electric potential (also called the electric field potential, potential drop, the electrostatic potential) is the difference in electric potential energy per unit of electric charge between two points in a static electric …

The relation between electric field and potential gradient can be derived by analyzing how the electric potential changes with respect to distance. In physics, especially in class 12, this relation helps to …

In this section, we will explore the relationship between voltage and electric field. For example, a uniform electric field E is produced by placing a potential difference (or voltage) Δ V across two parallel metal …

We have seen that the difference in electric potential between two arbitrary points in space is a function of the electric field which permeates space, but is independent of the test charge used to measure …

The electric field exists if and only if there is an electric potential difference. If the charge is uniform at all points, however high the electric potential is, there will not be any electric field.

Nov 12, 2025 · A charge moving in an electric field undergoes changes in potential energy. Moving "with" the electric field decreases potential; moving "against" the electric field increases potential.

Define electric potential and electric potential energy. Describe the relationship between potential difference and electrical potential energy. Explain electron volt and its usage in submicroscopic …

The formula E = ΔV / d expresses how large the potential difference in the unit of charge must be in order to produce a given electric field. Thus, if in a given region the electric field is zero, the potential …

Electric potential is similar to gravitational potential energy in physics, but instead of being related to mass and height, it is associated with electric charge and position in an electric field.
