The weather became hotter and hotter, and the mosquitoes began to agitate. Pick up the mosquito killing racket and wave two times toward the direction of the mosquito, "Crack", the mosquito was electrocuted. If we accidentally touch the metal net of the mosquito killing racket, will it be corona?

　　Where does the "crackling" sound of mosquito killing pats come from?

　　If you look carefully, you will find that the metal net of mosquito killing racket has three layers, the inner layer is in the middle of zui, and the inner layer is connected with the power supply. When mosquitoes fly between the outer and inner nets, they can almost be seen as conductors because of their good electrical conductivity.

　　The air molecules between the inner and outer nets are ionized under a strong electric field, forming an arc discharge, making a "crack" sound, and the energy generated by the discharge will electrocute mosquitoes.

　　Is it dangerous to meet a mosquito killing racket?

　　The voltage of the mosquito killing racket can reach 2000 volts, while the safe voltage our human body can withstand is less than 36 volts. Would it be dangerous if it touched the metal mesh?

　　The mosquito killing racket has internal and external nets. The external nets have low potential and will not form a loop with large terrain. Therefore, only touching the outside net will not cause electric shock. However, if you accidentally stick your finger in and touch the intranet, you will feel a slight electric shock.

　　That's because it's the current that makes people electrify. The high voltage and internal resistance of the mosquito killing racket, together with the resistance of our body, produce very little current, which is harmless to us (but enough to electrocute mosquitoes), and will only make you feel a slight tingling.

　　A hint

　　Although the current of the mosquito-killing racket is not enough to corona us, the slight inductance is also unpleasant. When using mosquito killing racket, try to avoid touching. It should also be noted that when electric mosquitoes turn off the power supply, there will be surplus electricity between the external network and the internal network.
