Van De Graaff Generator Hand Driven

• Mounted on base. • For the generation of electric charge. 

• Useful in electrostatics and for studying various phenomena associated with electric 

charge. 

• Comprises a near spherical dome supported on top of an insulated, clear Perspex pillar 

on the base. 

• Aremovable flat rubber belt rotates through rollers mounted at both the ends of Perspex 

pillar. 

• Lower roller shaft has a pulley driven by a hand operated crank through rubber belt. 

• The continuous rotation of the flat rubber belt results in the accumulation of charge on the 

dome, until electrical breakdown of air surrounding the sphere occurs. 

• With sufficient charge build up on the dome, bringing the earthed discharge sphere 

sufficiently close to it results in the transfer of charge from dome to ground in the form of 

electric spark. 

• Earthing terminal provided on the base. 

• Supplied with discharge sphere, mounted on a long insulated handle
