Insulators are materials that resist the flow of electric current. However, they can be charged through the accumulation of static electric charge on their surface or within their volume. This typically happens through processes like friction (triboelectric effect), contact with a charged object, or induction, which involve the transfer or redistribution of electrons, creating an imbalance of charge.
Which one of the following can charge an insulator ?
