Charged parallel conducting plates can store energy; this energy is actually stored in the . When a light bulb is connected across the plates, electrons flow from the negatively charged plate.

Capacitor

Explanation: A capacitor stores energy as charge in an electrical field between two conducting plates called electrodes which allows the flow of electrons between them.

Answer is capacitor.

Step-by-step explanation:

Capacitor is the device that stores the energy when connected to battery across two plates, the capacitor starts storing energy.

increases it

the entire statement is true and correct.  

there's no diagram, nothing is illustrated, and no question is asked.
