The electrical potential, also known as voltage, can be determined using the relationship between electric power and electric current.

Ohm's law states that the electric current passing through a conductor between two points is directly proportional to the voltage across the two points, and inversely proportional to the resistance between them. Mathematically, this can be expressed as:

V = I * R

Where V is the voltage, I is the electric current, and R is the resistance.

We can rearrange Ohm's law to solve for voltage:

V = P / I

Where P is the electric power, which is the product of the electric current and the voltage:

P = I * V

Therefore, we can substitute P / I for V in the equation above, giving us:

V = P / I

This equation allows us to calculate the voltage (or electrical potential) given the electric power and electric current.

An alternative formula for determining the electric potential can be derived from:
$$P$$ $$=$$ $$V$$ $$\cdot$$ $$I$$
$$V$$: the electric potential
$$P$$: the electric power
$$I$$: the electric current
The SI unit of electric power is: $$watt\text{ }(W)$$
