Spark generator. An alter.nating current power source with a condenser discharging across a spark gap.
Sparking at bnashes. (Elee.) Small sparks or flashes between commutator and brush due to poor
contact, improper position of brush, irregular surface, dust on commutator, etc.
Spark plug. (Auto.) A device for conducting the high-tension current to the combustion space where the charge is fired by the spark as it jumps the gap of the plug.
Spark-plug electrodes. (Auto.) The metal points between which the electric spark jumps. Also the metal conductor which passes through the center of the spark plug insulator.
