VAN DE GRAFF Generator

By Gary Zhong


What is an ATOM?


What is an atom made of?

  • 1. Protons: positive charge

  • 2. Electrons: negative charge

  • 3. Neutrons: no charge


Analogy: Planets orbiting the sun


Where are the basketballs and tennis balls located?


“Like charges repel, opposite charges attract”


Glass rod and silk cloth demo


Hair and comb demo

  • Combing your hair moves electrons from your hair to the comb

  • The comb will now have an electric static charge


What is a Van de Graff Generator?

The basic fundamental principle behind this

apparatus is separating opposite charges at

both ends of the rubber belt


Key Materials

  • Motor

  • Belt

  • Metal sphere

  • Rollers and Brushes


How it works!


Zoom in on our hair


Hair raising demo


Electric spark demo


Has anyone felt a shock on dry winter days?

THE SAME PRINCIPLE APPLIES
