The electrical potential can be determined using electrical capacitance and electric charge by using the formula:

Electric potential = Electric charge / Electrical capacitance

This formula shows that the electrical potential is directly proportional to the electric charge and inversely proportional to the electrical capacitance. The electrical potential is the measure of the electric potential energy per unit charge in an electric field. It is denoted by the symbol V and its unit is volt (V).

The electrical capacitance, on the other hand, is the ability of a system to store an electric charge. It is the ratio of the electric charge stored on one plate of a capacitor to the potential difference between the plates. It is denoted by the symbol C and its unit is farad (F).

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

\(C\) \(=\) \(\dfrac{Q}{V}\)

\(V\): the voltage

\(C\): the electric capacitance

\(Q\): The electric charge

The SI unit of electrical capacitance is: \(farad\text{ }(F)\)
