spark-gap

A technician adjusts the spark-gap in an electrical experiment.

Definition

1. Noun:
   • An electrical gap: "spark-gap" refers to an air gap between two electrodes across which a spark can pass, typically used in electrical circuits or devices to produce a spark or to protect against overvoltage.

Usage Examples

• Noun:
  • The technician adjusted the spark-gap to ensure the engine would ignite properly. (The gap between electrodes was set for correct spark generation.)
  • A spark-gap is often used in early radio transmitters to create high-frequency oscillations. (The device relies on a spark jumping across the gap.)

Advanced Usage

• "spark-gap transmitter": a type of radio transmitter that uses a spark-gap to generate radio waves.

  • The spark-gap transmitter was one of the first practical devices for wireless communication. (It produced sparks across a gap to emit signals.)

• "spark-gap protection": a method of safeguarding electrical equipment by using a spark-gap to divert excess voltage.

  • The circuit includes spark-gap protection to prevent damage from lightning strikes. (The gap allows a spark to discharge dangerous voltage safely.)

Variants and Related Words

• Spark gap (also written as two words): same meaning as "spark-gap".

  • The spark gap must be cleaned regularly to maintain performance. (The gap between electrodes needs maintenance.)

• Gap (n): a space or interval between two objects.

  • The gap between the electrodes is critical for spark formation. (The distance influences electrical discharge.)

Synonyms

• Discharge gap: a gap designed for electrical discharge.
• Air gap: a space filled with air between conductors.
