WebDec 11, 2016 · Charging by conduction is as follows: imagine having an electroscope and you place a charged metal rod (negative in this case = excessive electrons) to a neutral knob of an electroscope and the electrons from the charged rod will transfer to the entire length of the electroscope. 2.) WebDec 1, 2024 · Charging by friction: This kind of charging is done by rubbing one material with another. The most common examples are rubbing glass with silk, and ebonite (a kind of hard rubber) with wool. When a glass rod is rubbed with a piece of silk, negative charges are transferred from glass to silk. Web1 There are many materials that can be charged by triboelectric effect.
