From The Collaborative International Dictionary of English v.0.48 [gcide]:

  capacitor \ca*pac"i*tor\ (k[.a]*p[a^]s"[i^]*t[~e]r), n.
     a device used in electronic circuits to hold electrical
     charge, consisting of two conducting plates separated by a
     nonconducting (dielectric) medium; it is characterized by its
     capacitance.
  


     Syn: condenser, electrical condenser.

From WordNet (r) 2.0 [wn]:

  capacitor
       n : an electrical device characterized by its capacity to store
           an electric charge [syn: {capacitance}, {condenser}, {electrical
           condenser}]

From The Free On-line Dictionary of Computing (27 SEP 03) [foldoc]:

  capacitor
       
           An 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.
