Answer: The potential of electrons in a circuit can be increased by the action of the battery.
Step-by-step explanation:
A battery is a source of energy. It provides push to voltage so that the current can flow in the circuit.
For example, the electrical energy is used by the bulb connected in the circuit. The electrical energy is provided by the battery. If the energy of the battery is used up then no current will flow in the circuit. Then the bulb will not glow in this case.
Therefore, the potential of electrons in a circuit can be increased by the action of the battery.
