Ohm's Law relates the electric current flowing through a conductor to the potential difference (voltage) applied across its ends. Electric potential, also known as voltage, refers to the amount of work required to move an electric charge from one point to another in an electric field.

In the context of Ohm's Law, the electric potential difference (voltage) is directly proportional to the electric current and the resistance of the conductor. This means that if the voltage is increased, the current flowing through the conductor will also increase, and vice versa. However, if the resistance of the conductor is increased, the current flowing through it will decrease for a given voltage, and vice versa.

Ohm's Law is used in many applications, including the design of electrical circuits and devices, such as resistors and voltage regulators. Understanding electric potential and Ohm's Law is crucial for the study and application of electrical engineering and physics.

The formula for determining the voltage using Ohm's law is defined as:
\(V\) \(=\) \(I\) \(\cdot\) \(R\)
\(V\): the electric potential
\(R\): the electric resistance
\(I\): the electric current
The SI unit of voltage is: \(volt\text{ }(V)\)
