Friction is a source of which type of electricity?

Friction is responsible for generating static electricity. This phenomenon occurs when two materials are rubbed together, causing electrons to transfer from one material to the other. This transfer of electrons results in one object becoming positively charged and the other negatively charged, creating an imbalance of electric charge. Static electricity can build up and remain on the surface of an object until it is discharged, for example, when you touch a metal doorknob after walking on a carpet. The effects can be observed through sparks or static cling. Understanding static electricity is important for linemen and other professionals working around electrical systems, as static discharge can pose risks in certain conditions.
