The series combination of two or three capacitors resembles a single capacitor with a smaller capacitance. Generally, any number of capacitors connected in series is equivalent to one capacitor whose capacitance (called the equivalent capacitance ) is smaller than the smallest of the capacitances in the series combination.
A capacitor is a device used to store electric charge. Capacitors have applications ranging from filtering static out of radio reception to energy storage in heart defibrillators. Typically, commercial capacitors have two conducting parts close to one another, but not touching, such as those in Figure (PageIndex{1}).
Capacitance is the ability of an object to store an electrical charge. While these devices'' physical constructions vary, capacitors involve a pair of conductive plates separated by a dielectric material. This material allows each plate to hold an equal and opposite charge. This stored charge can then release as needed into an electrical circuit.

The voltage rating indicates the maximum voltage the capacitor can handle, marked as a number followed by "V". Tolerance shown as a percentage, indicating how much the actual capacitance can vary from the marked value. Polarized capacitors will have a plus (+) or minus (-) sign, or a stripe indicating the negative leg. 3. How to Calculate

Most capacitors contain at least two electrical conductors, often in the form of metallic plates or surfaces separated by a dielectric medium. A conductor may be a foil, thin film, sintered bead of metal, or an electrolyte. The nonconducting dielectric acts to increase the capacitor's charge capacity.
This technique of analyzing the combinations of capacitors piece by piece until a total is obtained can be applied to larger combinations of capacitors. If a circuit contains a combination of capacitors in series and parallel, identify series and parallel parts, compute their capacitances, and then find the total.
