Generators #420779

Product Description

Dynamo, Hand Operated

Rotation of the wheel results in the generation of alternating current (AC) and direct current (DC), output selectable through a sliding switch. The dynamo operation glows the small light bulb mounted on base. Output can also be had from a pair of 4mm sockets. The complete unit mounted on base.

Product Description

Van de Graff Generator, Hand Driven

completely hand operated, mounted on a base. A metal sphere surrounds the upper pulley assembly and charge accumulates on the sphere which is supported on an insulated transparent plastic column that also supports the pulley assembly at its upper end. The charge builds up until electrical breakdown of air surrounding the sphere occurs. Supplied with discharging sphere, metalized spheres, Faradays pail, head of hair, point discharger, electrical whirl and neon bulb.

Product Description

Wimshurst Electrostatic Generator

Electrostatic generator capable of producing spark up to 3 under favorable weather conditions. Two circular plastic plates, 24cm in diameter, each having metal sectors on their surface along the rims. Both the plates are mounted parallel to each other and rotate in opposite direction with a handle and belt system using joint less rubber belts through pair of large and small pulleys. Metal brushes, consisting of a bunch of laminated flexible strands, rub against the metal sectors and generate static charge.

This charge is conducted to leyden jar capacitors on connecting it to the ball shaped electrodes with a lever handle and gets accumulated on ball shaped dischargers. A pair of lever rods, ball shaped electrodes and a smaller pulley is mounted on an insulated arm. The pivoted section of electrodes has 4mm hole for electrical connection to operate various accessories. The complete assembly is mounted on a stable base with the help of a pair of legs. Complete with instructions.

Product Description

Van de Graff Generator, Motor Driven

Van de Graff Generator, Motor Driven

For study and demonstration of electrostatic phenomena. Motor Driven with a detachable metal dome for collecting charge. Complete with a removable, flat rubber belt, provision for mounting accessories on top of the dome, 4mm socket terminal on the base for attaching accessories and a discharge sphere with insulating stem. The charge is transferred from generator to the metallic dome surrounding the upper pulley through the motor driven rubber belt and two metallic combs. To attain high voltages, the lower portion of the sphere (Collar) is smoothly bent inside without sharp edges or bends. The complete unit is fitted on base and other insulating parts are made of Perspex.
