Friction is a source of what type of electricity?

Friction is a source of static electricity, which occurs when there is an accumulation of electric charge on the surface of objects. When two different materials are rubbed together, electrons can be transferred from one material to the other, creating a charge imbalance. This charge imbalance leads to an electrostatic buildup, which is characteristic of static electricity.

Static electricity is often experienced in everyday situations, such as when you rub a balloon on your hair and then see it stick to the wall or when you feel a shock after walking across a carpeted floor and then touching a metal doorknob. In contrast, dynamic electricity refers to the flow of electric charge, which is not related to the frictional processes leading to charge buildup. Current electricity involves the continuous flow of electrons through a conductor and is not relevant when discussing the effects of friction. Alternating current (AC) is a type of current electricity where the flow of electric charge changes direction periodically, further distinguishing it from the context of static electricity created by friction.
