When we think of a spark gap radio transmitter, most of us immediately imagine an early twentieth century ship’s radio room or similar. Most of us know these transmitters as the first radio ...

The simplest way to measure high voltage is by spark length. If your circuit has a spark gap then when a spark occurs, that’s a short-circuit, dumping all your built up charge. When your spark ...

The spark that ignites the fuel mixture jumps through a gap between these two electrodes. Both electrodes can wear away over time, extending the gap between them through which the spark jumps ...

With small engines, the chance of physical debris causing spark plug failure shouldn’t be ignored. The plug might have any of ...

create the electric spark required to ignite the compressed air-fuel mixture in gas-powered engines. The right type of plug and the size of the gap between the electrodes at the tip are specified ...
