Cutting edge Discharge - Customization of Science Museum Exhibitions, Campus Community Science Popularization Equipment, Source Manufacturer of Science Exhibitions Description and Introduction of Scientific Principles:
Operating instructions: Press the "Start" button and observe the discharge phenomenon at the tip of the metal rod. Function Overview: Exhibitions consist of needle shaped metal electrodes, high-voltage generators, rotating motors, and operating buttons. Press the "start" button, and the motor drives a set of needle shaped metal electrodes to rotate. As the two needle shaped electrodes gradually approach, discharge occurs between the tips of the two electrodes. The distribution of charges on a conductor is related to its surface shape. In sharp areas of the conductor surface, the distribution of charges is relatively dense. When the charges accumulate to a certain density, a large electric field is generated, which can penetrate the air. Two electrodes in the exhibits, one connected to high voltage and the other connected to ground. Two pointed needles gradually approach, and under the action of a strong electric field, the air near the tips is ionized, producing discharge sparks and making a crackling sound.
