Friction causes static electricity.
Static electricity is the result of an imbalance between negative and positive charges in an object. These charges can build up on the surface of an object until they find a way to be released or discharged. One way to discharge them is through a circuit.
The rubbing of certain materials against one another can transfer negative charges, or electrons. For example, by rubbing your shoe on the carpet as you walk, your body collects extra electrons. The electrons cling to your body until they can be released.
Touching another object, such as you touch your furry pet animal, you will feel an electric shock. However, this electric shock is only the surplus electrons being released from you to your pet. This can also as you rub your feet against the floor and then touch a metal doorknob.
Many people also experience hair-raising phenomena.
When a person removes their hat from their head, static electricity can cause the hair to stick up. Both the hair and the hat have the same electric charge, and like charges repel each other.
Another static electricity experiment is to rub a balloon surface against your clothes and then allow the balloon to stick to the wall surface.
The balloon surface is receiving surplus electrons, or negative charge, and making the balloon surface more negatively charged than the wall surface. The balloon surface will stick to the wall surface.
Other examples of static electricity cause by friction include:
Rubbing a balloon surface against your hair, causing your hair to stick to the balloon.
Fabric clothes in a dryer machine can build up static electricity as the machine spins and the clothes rub against each other constantly.
Lightning occurs when there is a static buildup of electric charge in clouds, and the lightning is discharged toward the ground surface.
The use of a hair comb can build up static electricity, and enable the comb to pick up small pieces of paper.
A photocopier uses static electricity and light to create paper copies of documents with the opposite charges of the print toner and paper.
Mobile phone touch screens also use static electricity to operate. The electric charge in your finger is opposite to the charge of the tiny wires inside the touch screen of the phone, creating an electric circuit when your finger touches the screen.
Many materials used in industry produce too much static electricity and proper management of this issue can reduce the problem.
