In a uniform electric field, the electric potential, often denoted as "V," is a scalar quantity that represents the electric potential energy per unit charge at a particular point in space. It indicates the work done by an external force in moving a positive test charge from a reference point (usually at infinity) to the given point within the electric field.
Mathematically, the electric potential "V" at a point in a uniform electric field can be expressed as:
V = -E * d
Where:
V is the electric potential at the point.
E is the magnitude of the electric field strength.
d is the distance from the reference point to the point where the potential is being measured.
It's important to note that electric potential is a scalar quantity and doesn't have a specific direction. Unlike electric field, which is a vector quantity and has both magnitude and direction, electric potential is concerned only with the magnitude of the electric potential energy per unit charge at a point.
The unit of electric potential in the International System of Units (SI) is the volt (V), where 1 volt is equal to 1 joule of electric potential energy per coulomb of charge.
