The electrical potential difference that drives current through a circuit is called

Explanation:
Voltage is the driving push that moves electric charges through a circuit. It is the electric potential difference that provides the energy to push charges and create current. Current is the flow of those charges, while resistance is what slows or restricts that flow, depending on the material and conditions. Power describes how quickly energy is transferred, not the driving force itself. In simple terms, the greater the voltage for a given resistance, the larger the current, which is why the term for the driving potential difference is voltage.
