Jacob's Ladder - Customized 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 arc changes. Function Overview: Exhibitions consist of horn shaped electrodes and a start button. Pressing the button, you will see the air at the lower end of the horn shaped electrode being broken down to form an arc, and the arc continues to climb upwards. When it reaches a certain height, it will disconnect, and a new arc will immediately form at the bottom. What's the secret behind this? Two sheep horn shaped electrodes with narrow bottom and wide top, one connected to high voltage and the other to ground. When the voltage between the two electrodes is high enough, the air at the narrow bottom of the electrode is broken down into a conductor, generating an arc. Due to the high temperature at the bottom during the discharge process, an upward airflow is formed, which drives the arc to continuously climb upwards. When the arc reaches a certain height and the electrode spacing exceeds the critical distance for "breakdown", the arc is extinguished. In this cycle, an arc discharge phenomenon resembling a ladder is formed, similar to the ancient Greek myth of the "Jacopo ladder". Electric arc discharge often occurs in the power system, and if the arc cannot be eliminated in time, it may burn out electrical equipment. Electric arc discharge can also be used by people. Welding is the process of using the high temperature generated by an arc to melt metal and weld objects together.
