Electrostatic Generator Equipment for Experimental Physics

The Electrostatic Generator: A Captivating Demonstration of Static Electricity

Specification: The device measures 28.5 x 20 x 33 cm, with a disk diameter of 24 cm.

Package Includes: 1 x Electrostatic Generator

Principle of Operation: The machine's operating principle is based on two counter-rotating disks made of insulating material. Each disk has several metal segments, called sectors, attached to it. As the sectors pass one another, they induce a charge imbalance. This imbalance is then drained off at the collecting electrodes.

Construction: The device features a number of metal foil sectors pasted onto an acrylic disc. Two sets of brushes are mounted on the charge collectors, one on the front and another on the rear disc. When the discs are rotated, the brushes collect the electrostatic charge from the metal foil, which is then transferred and stored in a Leyden jar capacitor. Once a very high voltage is achieved, electrostatic breakdown occurs, and a spark can be seen and heard between the electrodes.

Setup: 1. Set the gap between the two electrodes to about 1-2 inches. 2. Rotate the handle slowly at first, then gradually increase the rotation. 3. Once the voltage of the capacitor is high enough to overcome the electrostatic breakdown at the electrodes, discharge will occur, and a spark will be seen or heard. 4. After completing the experiment, discharge the electrodes and both capacitors using the metal "Y" handle.

Precautions: 1. Do not touch the metal parts while operating the machine, as it generates high voltage. 2. Remember to discharge the electrodes and capacitors using the metal "Y" handle after the experiment. 3. Do not rotate the handle too vigorously, as the pulley system may get damaged. 4. If no spark is seen or heard, check for moisture entrapping the brushes. The machine may be kept in the sun or near a heating device to remove the moisture.

Experiment Applications: The static machine is used in electrostatic experiments to generate a large amount of charge and high voltage (up to tens of thousands of volts). It can be combined with other instruments to study charge distribution on conductor surfaces, power lines, electrostatic fields, point discharge, and vacuum tube discharge.

Recreate Lightning: This generator is an ideal classroom demonstration device for electrical and physics experiments, capturing students' imagination by recreating the mesmerizing phenomenon of lightning.

Working Principle: The generator uses the induction effect to produce static electricity. When the two electrophorus disks spin, the charged system, especially the ball part on the discharge fork equipped with an insulated handle, will gather a significant amount of electric charge.

Features: The conductive layer of the plate is coated with a durable material, overcoming the shortcomings of aluminum foil that is easily detached. This improvement enhances the static generating performance, allowing the machine to generate static even in humid or rainy conditions.
