 for capacitor
From The Collaborative International Dictionary of English v.0.48 :

  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.
          [WordNet 1.5 +PJC]

From WordNet (r) 3.0 (2006) :

  capacitor
      n 1: an electrical device characterized by its capacity to store
           an electric charge [syn: capacitor, capacitance,
           condenser, electrical condenser]

From The Free On-line Dictionary of Computing (30 December 2018) :

  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 glitches.
