VAN DE GRAAF GENERATOR(H/DRIVEN) – GUPTA BRAND 8006050

Hand operated on base. The generator is self exiting and charge separation occurs. A metal sphere surrounds the upper pulley assembly and charge accumulates on the sphere, which is insulated by a plastic column supporting the pulley assembly. The charge builds up untill electrical breakdown of air surrounding the sphere occurs. Supplied with a discharging sphere.
