What are capacitors? In the realm of electrical engineering, a capacitor is a two-terminal electrical device that stores electrical energy by collecting electric charges on two closely spaced surfaces, which are insulated from each other. The area between the conductors can be filled with either a vacuum or an insulating material called a dielectric.
A capacitor is a device capable of storing energy in a form of an electric charge. Compared to a same size battery, a capacitor can store much smaller amount of energy, around 10 000 times smaller, but useful enough for so many circuit designs.
A capacitor is a device that stores electrical energy for a short time. Capacitors consist of two metal plates with a material called a dielectric in between. When connected to power, these plates hold opposite electrical charges. Later on, the capacitor can release this energy into the circuit.

In electrical circuits, the capacitor acts as the water tank and stores energy. It can release this to smooth out interruptions to the supply. If we turned a simple circuit on an off very fast without a capacitor, then the light will flash. But if we connect a capacitor into the circuit, then the light will remain on during the interruptions ...
A capacitor is an electrical component that stores charge in an electric field. The capacitance of a capacitor is the amount of charge that can be stored per unit voltage. The energy stored in a capacitor is proportional to the capacitance and the voltage.
A capacitor is a device that stores energy. Capacitors store energy in the form of an electric field. At its most simple, a capacitor can be little more than a pair of metal plates separated by air. As this constitutes an open circuit, DC current will not flow through a capacitor.
Capacitors come in various shapes. In electrical circuits, capacitors are frequently used to block direct current (dc) while permitting alternating current (ac) to flow. Some digital multimeters offer a capacitance measurement function so technicians can: Identify an unknown or unlabeled capacitor. Detect open or shorted capacitors.
