Electrostatics facts for kids
Electrostatics is the study of electric charges that are not moving. You might know it better as static electricity.
Static electricity happens when electric charges build up on the surface of objects. This often occurs when two different surfaces touch each other and then separate.
Tiny electric particles, called charges, move between the surfaces. We usually notice static electricity when one of the objects does not let electricity flow easily. This is because the charges get "stuck" on that object for a while.
These charges stay on the object until they can move away. They might slowly go into the ground or quickly jump to another object. A common example is a static 'shock'. This happens when charges built up on your body suddenly jump to another object, like a doorknob.
What are Examples of Static Electricity?
Static electricity is all around us! Here are some common examples you might have seen:
- When you pull plastic wrap from its roll, it often sticks to your hand. This is due to static charges.
- Sometimes, explosions can happen in grain silos. This can be caused by static electricity building up in the grain dust.
- Static electricity can damage sensitive electronic parts during manufacturing. It can also affect how photocopiers work.
