Van de Graaff Generator Motor Driven

The Van de Graaff Generator is an electrostatic generator that uses a moving belt to accumulate and transfer electric charge to a hollow metal dome mounted on an insulated column, producing a very high electrical potential. This physics laboratory equipment is useful for demonstrating important electrostatic principles such as charge accumulation, potential difference, capacitance, resistivity, and electrical discharge. It is suitable for practical demonstrations and experiments where a continuous high-voltage source is required. The unit is mounted on a stable base with a smooth-running AC motor operating at 220 V AC, 50 Hz. The conductor sphere is detachable, the motor speed can be controlled, and a separate discharge sphere is provided on an insulated rod. Various accessories are included for demonstrating and investigating the nature and behavior of static electric charge. Manufactured by Atico Export India for physics laboratory applications.
