Static Electricity: Surface Charge Buildup

The video tutorial explains the concept of static charge, which occurs on the surface of objects, and contrasts it with current electricity, where charge flows through a medium like a wire. It further describes how static charge can be generated on electrical insulators, such as a balloon, by rubbing them on surfaces like fur.

What role does friction play in the generation of static electricity?

Describe the process of generating static electricity using a balloon.
