Normal Spark Electricity runs along circuits and back to the main grid without interruption. When a device is plugged into the outlet, some of the electricity transfers from the outlet to the device. When you unplug it, you’re breaking the electric contact, causing the spark.
Is it dangerous if a plug sparks?
When something is plugged in, or turned on, some of that very fast, hot electricity transfers from the outlet into the appliance, light, computer or whatever.

What causes electrical sparks?
An electric spark is an abrupt electrical discharge that occurs when a sufficiently high electric field creates an ionized, electrically conductive channel through a normally-insulating medium, often air or other gases or gas mixtures.
Why do plugs sometimes spark?
Harmless sparks- When an appliance is plugged in to the mains, or turned on, electricity is transferred from the circuit, into the appliance. This can be a rapid process, and can sometimes result in a small, brief spark of static electricity. This is not something to worry about in most cases.

How does a spark start an explosion?
The explosion is set off by an electrostatic spark. When the mixture ignites, the rapid increase in temperature brings about a huge increase in gas pressure. If the burning vapour were to be confined the resulting rise in pressure could destroy the chamber with a loud explosion.
What does it mean if a light switch sparks?
The light switch contacts are worn out – A sparking light switch results if one of the contacts in the light switch are simply worn out.
