spark coil
Noun: An induction coil specifically designed and used to generate high-voltage electrical sparks.
This is a technical term used primarily in electrical engineering, physics, and historical contexts (e.g., early radio transmission, ignition systems). It refers to the complete device or component whose primary function is spark generation. * The antique radio's transmitter relied on a spark coil. * To demonstrate the principle of electromagnetic induction, the professor used a spark coil.
The term is often associated with specific historical applications. * Spark-gap transmitter: Early radio transmitters that used a spark coil to generate radio frequency oscillations. * Marconi's early experiments in wireless telegraphy utilized a spark coil as part of a spark-gap transmitter.
- Induction coil (n): A more general term for a coil that produces a high-voltage pulse from a low-voltage direct current supply. A spark coil is a type of induction coil.
- Ignition coil (n): A modern, specialized type of induction coil used in internal combustion engines to create the spark for the spark plugs. This is a direct functional descendant of a spark coil.
- Ruhmkorff coil (n): A historical term for a particularly efficient type of induction/spark coil, named after its inventor.
