Corona Discharge
Operation: Press the "Start" button and observe the tip discharge phenomenon of the metal rods. Function Overview: The exhibit consists of needle-shaped metal electrodes, a high-voltage generator, a rotating motor, and an operation button. Press the "Start" button, and the motor drives a set of needle-shaped metal electrodes to rotate. As the two needle electrodes gradually approach each other, a discharge phenomenon occurs between the tips of the two electrodes. Scientific Principle: The distribution of electric charge on a conductor is related to its surface shape. At sharp points on the conductor surface, the charge distribution is denser. When the charge accumulates to a certain density, a strong electric field is generated, breaking down the air. In the exhibit, one of the two electrodes is connected to high voltage, and the other is grounded. As the two sharp needles gradually approach, under the action of the strong electric field, the air near the tips is ionized, producing discharge sparks and a crackling sound.
