Learn about the three main methods of charging objects: by friction, by conduction (contact), and by induction. Understand how electrons transfer between materials and how objects become positively or negatively charged.

Test your knowledge of different methods of charging objects, electron affinity, and basic electrostatics concepts including charging by friction, conduction, and induction.
