In electrical engineering, a capacitor is a device that stores electrical energy by accumulating electric charges on two closely spaced surfaces that are insulated from each other. The capacitor was originally known as the condenser, a term still encountered in a few compound names, such as the condenser microphone. It is a passive electronic component with two terminals.

Parallel-Plate Capacitor: In a capacitor, the opposite plates take on opposite charges. The dielectric ensures that the charges are separated and do not transfer from one plate to the other. The purpose of a capacitor is to store charge, and in a parallel-plate capacitor one plate will take on an excess of positive charge while the other becomes more negative.

Capacitor vs. Battery: What''s the Difference?
We don''t use capacitors as batteries because they can''t store as much energy as batteries, and they also can only handle current in one direction. Additionally, capacitors are usually much smaller in size and weight than batteries, which means they are not suitable for applications that require a lot of energy or that need to be charged or discharged over a long …
Physics A level revision resource: Introduction to capacitors
Unlike the battery, a capacitor is a circuit component that temporarily stores electrical energy through distributing charged particles on (generally two) plates to create a potential difference. A capacitor can take a shorter time than a battery to charge up and it can release all the energy very quickly.

As charge increases on the capacitor plates, there is increasing opposition to the flow of charge by the repulsion of like charges on each plate. In terms of voltage, this is because voltage across the capacitor is given by (V_c = Q/C), where (Q) is the amount of charge stored on each plate and (C) is the capacitance .
