When an electrical circuit is switched off sometimes sparking is observed explain why?
Answers
⭐⭐⬅️ Answer ➡️➡️➡️➡️As you open the switch to turn off the light, you are pulling two conductors apart to break the circuit. As the conductors begin to separate, the high voltage (115 or 230V)can cause breakdown of some of the air molecules in the gap and a small amount of current flows through the ionized air and you see a “spark

Answer:
When an electrical circuit is switched off sometimes sparking is observed because the switch's gap creates a very significant induced emf. Sparking happens as a result of this significantly induced emf.
Explanation:
When we break a circuit, a lot of voltage is created in the gap of the circuit that is being broken. Suddenly, the electric charges pass through this little air gap. Although air is a poor conductor of electricity, a high voltage ionizes its particles, creating a temporary conducting channel for the electric charges. As a result, the air becomes hotter, and we perceive this as a bright spark.
