The electric power can be determined using the relationship between the electrical potential and the electric resistance.

The formula for electric power is:

P = V^2 / R

where P is the electric power, V is the electrical potential, and R is the electric resistance.

To find the electric power using the electrical potential and electric resistance, we can rearrange the formula as:

P = V^2 / R

For example, if the electrical potential is 10 volts and the electric resistance is 5 ohms, the electric power can be calculated as:

P = (10 volts)^2 / 5 ohms = 20 watts

Therefore, the electric power is 20 watts.

The formula for determining electric power using voltage and resistance is defined as:
\(P\) \(=\) \(\dfrac{V^2}{R}\)
\(P\): the electric power
\(R\): the resistance
\(V\): the electric potential
The SI unit of electric power is: \(watt\text{ }(W)\)
