Electric potential can be determined using the equation:

electric potential = electric energy / electric charge

where electric energy is the amount of energy carried by an electric charge as it moves through an electric potential difference. Electric charge is the amount of charge present in a circuit or object.

This equation is derived from the definition of electric potential, which is the electric potential energy per unit charge. Electric potential energy is the work done in moving a charge against an electric field from one point to another. So, electric potential is the work done per unit charge in moving a charge from one point to another.

In practical terms, this equation can be used to calculate the electric potential at a certain point in a circuit or system, given the amount of electric energy and electric charge present. For example, if we know the amount of energy required to move a certain amount of charge from one point to another in a circuit, we can use this equation to determine the electric potential at that point.

Overall, the equation relating electric potential to electric energy and electric charge is a fundamental relationship in the study and application of electricity and electronics. It allows us to understand and quantify the behavior of electrical systems, and to design and optimize them for various applications.

An alternative formula for determining the electric potential can be derived from:

\(E\) \(=\) \(V\) \(\cdot\) \(Q\)

\(V\): the electric potential

\(Q\): The electric charge

\(E\): the electric energy

The SI unit of electric energy is: \(joule\text{ }(J)\)
