WebOct 29, 2024 · Static electricity occurs when charge builds up in one place. Objects typically have an overall charge of zero, so accumulating a charge requires the transfer of electrons from one object to another. There are several ways to transfer electrons and thus build up a charge: friction (the triboelectric effect), conduction, and induction. WebAug 20, 2015 · 31 3. Move any object along another object in normal conditions and you will always get some friction, even a small amount. – user81619. Aug 20, 2015 at 20:18.
