Sparking
Sparking is the brief electrical discharge that occurs when a current crosses a gap between two conductive electrodes, ionizing the surrounding gas and forming a conductive plasma. Sparks are transient events that produce light, heat, and sound and may occur in switches, relays, circuit breakers, or in high-voltage equipment when insulation is compromised.
In electronic equipment, sparking can be due to contact bounce, contamination, or insulation failure; it can
Sparking is essential in spark-ignition engines; a spark from a spark plug ignites the air-fuel mixture.
Sparks also occur in metalworking, for example during grinding or wire brushing, and controlled sparking is
Safety and prevention: use proper enclosures, spark suppressors, guards, and moisture control; ensure equipment is properly
