In Mathematics and Physics (especially Electronics), a region is called equipotential if every point in it is at the same potential. This usually refers to a scalar potential, although it can also be applied to vector potentials. Often, equipotential surfaces are used to visualize an (n)-dimensional scalar potential function in (n-1) dimensional space.

Since antiquity, people have tried to understand the behavior of matter: why unsupported objects drop to the ground, why different materials have different properties, and so forth. ... Two digital voltmeters The field of electronics is the study and use of systems that operate by controlling the flow of electrons or other electrically charged particles in devices such as thermionic valves and semiconductors. ... It has been suggested that this article or section be merged with Scalar potential. ... It has been suggested that this article or section be merged with Potential. ... In vector calculus, a vector potential is a vector field whose curl is a given vector field. ... In fluid mechanics, equipotentials are lines or surfaces of equal head that are in direct relation to pressure. ... In common usage, the dimensions (from Latin measured out) of an object are the parameters or measurements required to define its shape and size, that is, usually, its height, width, and length. ... In mathematics, a function is a relation, such that each element of a set (the domain) is associated with a unique type of another (possibly the same) set (the codomain, not to be confused with the range). ...

For scalar potentials, the gradient in a equipotenial region is zero, since there is no change in the value of the potential. This is important in physics because the force on a body is often determined by the gradient of that force's potential function. In the above two images, the scalar field is in black and white, black representing higher values, and its corresponding gradient is represented by blue arrows. ... In physics, a force is an external cause responsible for any change of a physical system. ...

For example, there is zero electric field in an equipotential region (that is, a region of constant voltage). A charged particle in such a region experiences no electric force. Thus, there is no electric current between two points of equal voltage because there is no force driving the electrons. In physics, an electric field or E-field is an effect produced by an electric charge that exerts a force on charged objects in its vicinity. ...

Likewise, a ball will not be pulled down by the force of gravity if it is resting on a flat, horizontal surface. This is because points on the surface are at equal gravitational potential. Gravity is the force of attraction between massive particles. ... Horizontal is an orientation relating to, or in parallel with the horizon, and thus perpendicular to the vertical. ... In physics, gravitational potential is the measure of potential energy an object possesses due to its position in a gravitational field. ...

Note that an equipotential regions might referred to as 'of equipotential' or simply be called 'an equipotential'.
