From The Collaborative International Dictionary of English v.0.48 :

  Electricity \E`lec*tric"i*ty\ ([=e]`l[e^]k*tr[i^]s"[i^]*t[y^]),
     n.; pl. Electricities ([=e]`l[e^]k*tr[i^]s"[i^]*t[i^]z).
     [Cf. F. ['e]lectricit['e]. See Electric.]
     1. (Physics) a property of certain of the fundamental
        particles of which matter is composed, called also
        electric charge, and being of two types, designated
        positive and negative; the property of electric charge on
        a particle or physical body creates a force field which
        affects other particles or bodies possessing electric
        charge; positive charges create a repulsive force between
        them, and negative charges also create a repulsive force.
        A positively charged body and a negatively charged body
        will create an attractive force between them. The unit of
        electrical charge is the coulomb, and the intensity of
        the force field at any point is measured in volts.

     2. any of several phenomena associated with the accumulation
        or movement of electrically charged particles within
        material bodies, classified as static electricity and
        electric current. Static electricity is often observed
        in everyday life, when it causes certain materials to
        cling together; when sufficient static charge is
        accumulated, an electric current may pass through the air
        between two charged bodies, and is observed as a visible
        spark; when the spark passes from a human body to another
        object it may be felt as a mild to strong painful
        sensation. Electricity in the form of electric current is
        put to many practical uses in electrical and electronic
        devices. Lightning is also known to be a form of electric
        current passing between clouds and the ground, or between
        two clouds. Electric currents may produce heat, light,
        concussion, and often chemical changes when passed between
        objects or through any imperfectly conducting substance or
        space. Accumulation of electrical charge or generation of
        a voltage differnce between two parts of a complex object
        may be caused by any of a variety of disturbances of
        molecular equilibrium, whether from a chemical, physical,
        or mechanical, cause. Electric current in metals and most
        other solid coductors is carried by the movement of
        electrons from one part of the metal to another. In ionic
        solutions and in semiconductors, other types of movement
        of charged particles may be responsible for the observed
        electrical current.

     Note: Electricity is manifested under following different
           forms: (a)
  
     Statical electricity, called also
  
     Frictional electricity or Common electricity, electricity
        in the condition of a stationary charge, in which the
        disturbance is produced by friction, as of glass, amber,
        etc., or by induction. (b)
  
     Dynamical electricity, called also
  
     Voltaic electricity, electricity in motion, or as a current
        produced by chemical decomposition, as by means of a
        voltaic battery, or by mechanical action, as by
        dynamo-electric machines. (c)
  
     Thermoelectricity, in which the disturbing cause is heat
        (attended possibly with some chemical action). It is
        developed by uniting two pieces of unlike metals in a bar,
        and then heating the bar unequally. (d)
  
     Atmospheric electricity, any condition of electrical
        disturbance in the atmosphere or clouds, due to some or
        all of the above mentioned causes. (e)
  
     Magnetic electricity, electricity developed by the action
        of magnets. (f)
  
     Positive electricity, the electricity that appears at the
        positive pole or anode of a battery, or that is produced
        by friction of glass; -- called also vitreous
        electricity. (g)
  
     Negative electricity, the electricity that appears at the
        negative pole or cathode, or is produced by the friction
        of resinous substance; -- called also resinous
        electricity. (h)
  
     Organic electricity, that which is developed in organic
        structures, either animal or vegetable, the phrase animal
        electricity being much more common.
        [1913 Webster]
  
     3. The science which studies the phenomena and laws of
        electricity; electrical science.
        [1913 Webster]
  
     4. Fig.: excitement, anticipation, or emotional tension,
        usually caused by the occurrence or expectation of
        something unusual or important.

From The Collaborative International Dictionary of English v.0.48 :

  electric charge \electric charge\, electrical charge \electrical
  charge\,
     same as electricity[1].
     [PJC] electric current

From WordNet (r) 3.0 (2006) :

  electric charge
      n 1: the quantity of unbalanced electricity in a body (either
           positive or negative) and construed as an excess or
           deficiency of electrons; "the battery needed a fresh
           charge" [syn: charge, electric charge]
