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.
Find V
Use this calculator to determine the electric potential when the electric power and current are given.
