Products are mainly composed of the machine base, a motor, a dry with incandescent lamp, organic glass cylinder, accumulator ball, adjusting screw, comb, belt wheel, rubber belt, discharge, discharge ball insulating rod. Instrument can produce tens of thousands of volts potential difference, as the electrostatics experiment of high voltage static power can be used to demo charge properties, distribution; electrostatic induction principle; display power line and tip discharge phenomenon. About 200 x 280 x 90mm.
