Question

The sum of charges on both plates of a capacitor is zero. What does a capacitor store?

Answer 1

Hint:Before we go into the question, let's have a look at what a capacitor is.A capacitor is a device that stores electrical energy in an electric field. It's a passive electrical component with two terminals. The term "capacitance" refers to the action of a capacitor.

Complete answer:
It is capable of storing a charge. One plate is positively charged, while the other is negatively charged, cancelling out the positive charge perfectly. As a result, the total is zero. An electric field exists between the oppositely charged plates. The capacitor's actions are manifested by this electric field: a difference in potential proportional to the charge, the maintenance of equal and opposite plate charges, and so on.

Additional information: Capacitors are useful in a variety of situations. They are employed in digital circuits, for example, to ensure that information saved in big computer memories is not lost during a brief loss of power; the electric energy stored in such capacitors keeps the information alive during the power outage. Capacitors are even more useful as filters, diverting stray electric signals and preventing damage to delicate components and circuits from electric surges.

Note:When a capacitor is exposed to strong currents, the capacitor may heat up and explode. Large amounts of energy can be stored in capacitors. When one capacitor in a bank fails inside, all of the other capacitors in the bank discharge into the fault, resulting in an explosion.
