Is it very dangerous to encounter mosquito swatters?

　　The voltage of mosquito swatter can reach 2000 V, and the safe voltage that our human body can bear is less than 36 v. Is it dangerous to touch the metal net?

　　There are internal and external nets in the mosquito swatter. The potential of the external net is low, and it will not form a circuit with the earth. Therefore, only touching the Internet will not cause electric shock. However, if you don't carefully put your finger in contact with the internal network, you will have a slight electric shock.

　　That's because it's the current that causes people to get electrocuted. The voltage of mosquito swatter is high, the internal resistance is large, plus the resistance of our human body, the current generated is very small, this current is not harmful to us (but enough to kill mosquitoes), it will only make you feel slight tingling.

　　Where does the crackling sound come from?

　　After careful observation, we can find that there are three layers of metal mesh of mosquito swatter, the middle layer is the inner layer, and the inner layer is connected with the power supply. When a mosquito flies between the outer net and the inner net, it can almost be regarded as a conductor because of its good conductivity.

　　The air molecules between the internal and external networks ionize under the extremely strong electric field, forming an arc discharge, making a "crackling" sound, and the energy generated by the discharge will kill the mosquito.

　　A reminder: Although the current of the mosquito swatter is not enough to corona us, this kind of slight electric shock is not good. Try to avoid touching when using mosquito swatter. It should also be noted that when the electric mosquito turns off the power, there will be extra power between the external network and the internal network.
