spark gap

A spark gap is a small space between two conductors that allows an electric spark to jump across when the voltage exceeds a certain level. This phenomenon occurs because the air in the gap becomes ionized, enabling electricity to flow. Spark gaps are used in various applications, such as in lightning protection systems, radio transmitters, and as safety devices in electrical equipment. They can help prevent damage from voltage spikes by diverting excess energy away from sensitive components. Essentially, spark gaps act as a controlled way to manage high-voltage situations.
