• The Color of this item is changed to Light Blue. Please make sure you know before you bid.
• Thank you very much!
• Item :
• 1.The two plates are supported in two rigid uprights and driven by belt in opposite direction.
• 2.They are heavy, high resistance plastic with sectors of aluminium sheet.
• 3.Two leyden jars (condensers) made form corning glass and aluminium foil.
• 4.The whole body is mounted on a plastic base nicely polished.
• Specification:
• Size(Length x Width x Height): 28.5 x 20 x 33 cm
• Disk Dia.: 24cm
• Principle:
• The operating principle of the machine is based on two counter-rotating disks made of insulating
• material. Each disk has several metal segments attached to it, called sectors. As the sectors pass
• one another, they induce a charge imbalance on one another. This imbalance is drained off at the
• collecting electrodes.
• Construction:
• A number of metal foil sectors are pasted on an acrylic disc. Two set of brushes are mounted on the
• charge collectors - one on the front and another on rear disc. When the discs are rotated, the brushes
• collect the electrostatic charge of the metal foil which is transferred and stored in the Leyden jar capacitor.
• When a very high voltage is achieved, electrostatic breakdown occurs and spark between the electrodes
• is seen and heard.
