The Nature of Electricity: Charging Objects

The video tutorial explains three methods of charging objects: friction, conduction, and induction. Friction involves rubbing objects together to transfer electrons, as demonstrated with a plastic rod and woolen cloth. Conduction requires direct contact, shown with a copper wire and battery. Induction charges objects without contact, illustrated by a comb and paper. Each method highlights different principles of electric charge transfer.

How does friction contribute to charging objects?

What is the effect of bringing a negatively charged comb close to neutrally charged paper?
