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.
Capacitors in Series and in Parallel: The initial problem can be simplified by finding the capacitance of the series, then using it as part of the parallel calculation. The circuit shown in (a) contains C 1 and C 2 in series. However, these are both in parallel with C 3.

Capacitors, also known as condensers, are devices that store electrical energy in an electric field. To put simply, capacitors are made by taking 2 conductors and place an insulator between the conductors. Thus, the ability to store energy is what makes capacitors unique. They are also one of the fundamental passive components.

In simpler terms, capacitors are physical devices, while capacitance is a measure of the charge storage capacity of a capacitor. The term "capacity" typically refers to the ability to hold or contain something, often in a broader context. In contrast, a capacitor specifically refers to an electronic component used to store electrical energy.

The insulator is also known as a dielectric, and it boosts a capacitor''s charging capacity. Capacitors are sometimes called condensers in the automotive, marine and aviation industries. The internal plates are wired to two external terminals, which sometimes are long and thin and can resemble tiny metallic antennae or legs. These terminals can ...
An AC ammeter connected in the circuit would indicate a current flowing through the capacitor, but the capacitor has an insulating dielectric between the two plates, so it is a displacement current that the ammeter records. The value of this current is affected by the applied voltage, the supply frequency, and the capacity of the capacitor.
