EXPLANATION OF TERMS.


      _Accumulator._—Another name for secondary batteries.

      _Alternate Current Dynamo._—Produces currents which are
    alternately positive and negative.

      _Amalgamation._—Zinc is protected from local action by
    having its surface coated with mercury.

      _Ampère._—The Unit of current. A volt divided by an ohm.
    (See Electrical Measurements, page 104.)

      _Ampère Meter._—An instrument used for measuring strength
    of current.

      _Anode._—The positive electrode or pole of a decomposing
    cell, the wire or plate connected to the copper or other
    negative element of a battery. In electro-plating, it is
    usually the soluble pole of the metal to be deposited.
    (_v._ Cathode.)

      _Arc._—The air space in which the electric light forms.
