Made inIndia

A hand-cranked Van de Graaff generator that builds a very high voltage at low current. No power supply is needed: turning the wheel runs a rubber belt that charges the metal dome.

How it works

Turn the driving wheel to run the rubber belt inside the Plexiglas column
Charge builds up on the removable metal dome
Swing the discharge sphere towards the dome on its arm and a spark jumps across

What students learn

Mechanical work can be used to separate electric charge
Charge collects on the outer surface of a metal dome
A spark is charge rushing through the air once the voltage is high enough

Try these experiments

Turn faster and see whether the spark gets longer
Hold a neon tube near the dome and watch it glow
Compare the spark with that of the motor-driven model

Curriculum fit
