Definition of "capacitor" |
A device consisting of two conducting surfaces separated by a layer of insulating material (dielectric)and having the ability of storing electric energy. Also called a condenser, the principal characteristics of which is the capacitance. / A capacitor is a passive electronic component that consists of two conductive plates separated by an insulating dielectric. A voltage applied to the plates develops an electric field across the dielectric and causes the plates to accumulate a charge. When the voltage source is removed, the field and the charge remain until discharged, storing energy. / A capacitor originally known as a condenser is a passive two-terminal electrical component used to store energy electrostatically in an electric field. The forms of practical capacitors vary widely, but all contain at least two electrical conductors Plates separated by a dielectric that is, insulator. The conductors can be thin films of metal, aluminum foil or disks, etc. / A device used to store an electric charge, consisting of one or more pairs of conductors separated by an insulator. / A magnetic core is a piece of magnetic material with a high permeability used to confine and guide magnetic fields in electrical, electromechanical and magnetic devices such as electromagnets, transformers, electric motors, generators, inductors, magnetic recording heads, and magnetic assemblies. It is made of ferromagnetic metal such as iron, or ferrimagnetic compounds such as ferrites. / an electronic component having capacitive reactance. |
