The current passing through the human body is determined by the applied voltage and human resistance, and only a voltage not exceeding 36 volts is safe.
When the human body passes through a current of less than 5 milliamperes, there is no danger. The resistance of dry human skin is generally above 10000 ohms, and the current passing through the human body at 36 volts is below 5 milliamperes. So, generally speaking, a voltage of 36 volts is safe for the human body. Therefore, a voltage below 36 volts is called a safe voltage, and only a voltage not exceeding 36 volts is safe.
The degree of harm of electric shock to the human body mainly depends on the magnitude of the current passing through the human body and the duration of electrification. The greater the current intensity, the greater the danger of death; The longer the duration, the greater the likelihood of death. Therefore, if someone is found to have an electric shock, the power should be immediately cut off, or an insulated object should be used to lift the power cord away from the patient's body.
