Jacob's Ladder
Exhibit Dimensions: Transport dimensions: 540×440×640mm, Display dimensions: 540×440×1450mm. Exhibit Composition: Consists of ABS plastic molded cabinet, ABS plastic molded pedestal, ABS milky white plastic molded operation countertop with color silk-screen flip-up instruction board, delay circuit, stainless steel illuminated self-reset metal button, leakage protector, horn electrodes, high-voltage discharge pack, acrylic cover, etc. Scientific Principle: This exhibit demonstrates the principle of air discharge. Air discharge occurs when high voltage is applied to two opposing electrodes and the applied voltage exceeds the dielectric strength of the gas, causing the gap between the electrodes to be broken down by discharge. In this exhibit, due to the special shape of the discharge electrodes, the arc takes a bow shape, and the current in the bow-shaped arc generates a magnetic field, which produces an upward electromagnetic force on the arc itself, so the arc is elongated and moves upward. When the arc is elongated to a certain length and the applied voltage cannot maintain the conditions required for arc generation, the arc extinguishes, and then a new arc breakdown occurs at the horn electrodes, repeating the above process. Operation: Press the 'Start' button; observe the changes in the high-voltage arc between the two horns.
