2 definitions found From WordNet r 1.6 [wn]: capacitor n : an electrical device characterized by its capacitance [syn: {condenser}, {electrical condenser}] From The Free On-line Dictionary of Computing (13 Mar 01) [foldoc]: capacitorAn electronic device that can store electrical charge. The charge stored Q in Coulombs is related to the capacitance C in Farads and the voltage V across the capacitor in Volts by Q = CV The basis of a {dynamic RAM} cell is a capacitor. They are also used for power-supply smoothing (or "decoupling"). This is especially important in digital circuits where a digital device switching between states causes a sudden demand for current. Without sufficient local power supply decoupling, this current spike" cannot be supplied directly from the power supply due to the inductance of the connectors and so will cause a sharp drop in the power supply voltage near the switching device. This can cause other devices to malfunction resulting in hard to trace {glitch}es. (1995-04-12)
