Lightning Rod Principle Demonstration Instrument Physics Teaching Instrument Tip Discharge Phenomenon and Lightning Formation Experiment Formation of Lightning Electrostatic

Specification:Size: Bottom box length 200mm* Bottom box width 130mm* Overall height 170mmMaterial: plastic bottom box, aluminum plate, metal componentsWeight:About 630gInstructions1. Adjust the metal ball and the lightning rod to the same height (about 5mm difference from the aluminum plate), and then connect the high-voltage output end of the high-voltage generator to the positive and negative poles of the lightning rod demonstration model. Turn on the power of the high-voltage generator, start from the lowest gear, and turn on the four gears (KV, 10KV, 20KV, 50KV) of the high-voltage generator respectively,Observe the strength of the spark phenomenon. When adjusted to the appropriate high voltage, a crackling sound can be heard, and a continuous discharge spark line is formed between the tip of the lightning rod and the aluminum plate, and the metal ball has no ignition phenomenon. This phenomenon explains that in an environment where high voltage exists, objects with a small cross-sectional area at the same height are easy to discharge, so the lightning rod should be pointed.2. Disconnect the power supply and lower the lightning rod to a difference of about 2mm from the metal ball. Turn on the power again, and observe that the discharge spark on the lightning rod weakens, but there is still no spark on the metal ball, indicating that within a certain distance, the discharge is still at the tip.

• *Lightning Rod Principle Demonstrator: Explore the phenomenon and regular characteristics of tip discharge, understand the causes of lightning formation and the working principle of lightning rods
• *The positive pole of the lightning rod principle demonstration model is connected to the metal ball and the lightning rod, and the negative pole is connected to the aluminum plate and the screw.
• *The principle of the lightning rod is to use the tip discharge phenomenon to release the electric charge induced by the thundercloud in the earth's atmosphere into the earth's ground in a timely manner,
• *At the same time, when lightning occurs, the lightning rod can also attract the discharge *channel of the lightning, so that the lightning current flows from the lightning rod into the earth's land
• *Note: During the experiment, connect the positive and negative poles of the demonstration model to a high-voltage generator, and observe the gap between the metal ball, the lightning rod and the aluminum plate.
