Electric potential is the amount of electric potential energy per unit charge at a point in an electric field. It is measured in volts (V). It tells us how much work is needed to move a charge from one point to another.
In an electric circuit, electric potential (voltage) creates a force that pushes charges, causing current to flow. Without a potential difference, no current will flow.
For example, in a battery, the positive terminal has a higher potential than the negative terminal. This difference in potential makes electrons move, powering electrical devices.
Electric potential is essential in electronic circuits, power generation, and transmission systems.
