the gap between two high-potential terminals a component of an ignition system; consists of two shaped electrodes and the space between them
The space filled with air or other dielectric between high potential terminals (as of an electrostatic machine, induction coil, or condenser), through which the discharge passes; the air gap of a jump spark
A gap in an otherwise complete electric circuit across which a discharge occurs at a prescribed voltage
space between two conducting electrodes across which an electrical or spark discharge can occur
