People are electrocuted because electric current passes through the human body, interfering with the generation and transmission of nerve electricity in the human body and destroying the activity capacity of tissues. In severe cases, it will directly generate large amounts of heat and burn human tissue.
Electricity in water is the same as electrification through a resistor. An electric field will be formed from the electrode, and there will be a voltage drop at a certain distance. When the human body is under this voltage, an instantaneous current will be generated inside the human body. Generally, for example, when the current is greater than 0.01 amp or exceeds the corresponding safety voltage of 36 volts and the direct contact voltage is 24 volts, it can destroy human mobility. tissues, cause pain and even lead to dangerous situations such as a choc and cardiac arrest.
So passing high voltage electricity through water will electrocute people. Children should not play with electricity or water casually.
