The Nature of Electricity: Charges in Action

The video tutorial explains the effects of charges using an electroscope. It describes how metal leaves inside a glass flask react to a negatively charged rubber rod and a positively charged glass rod. The metal leaves repel each other due to the transfer of charges via conduction, demonstrating the principle that like charges repel.

What occurs when a positively charged glass rod comes into contact with the electroscope?

Why do the metal leaves acquire a positive charge when the glass rod touches the electroscope?
