人体安全电压（Body safety voltage） Answer: the human body safe current: AC 10MA, DC 50MA. There are three kinds of safety voltage in human body: 12 volts, 24 volts and 36 volts. (editor in chief: ) In a humid environment, the bodys safety voltage is 12 volts. Under normal circumstances, the safety voltage of the human body shall not exceed 50 volts. Grounding measures should be taken when the voltage is over 24 volts. Because the key to electric death is the size of the current. Hair discharge clothing, when the spark voltage of tens of volts, but did not form a continuous current, so the electricity will not be dead. Therefore, specific problems are analyzed Under normal conditions (dry), the safety voltage is below 36V The more humid, the less resistance, the greater the voltage, that is, the greater the current 1 electric shock to peoples harm Electric shock is the pathological and physiological effect caused by electric current passing through the human body. Electric shock is divided into two kinds of electric injury and electric shock. Electrical injury is the injury of the electric current to the surface of the human body. It is often not life-threatening. An electric shock is an electrical current passing through the body Direct damage to the internal organization, it is dangerous injuries, often lead to serious consequences, electric shock can be divided into direct contact with electric shock and indirect contact shock. Direct contact shock is an electrical shock that occurs when a person is in direct contact with the live part of an electrical device or an electrical circuit. It is characterized by the contact voltage of the human body, that is, the voltage of the charged body touched by the human body; the grounding of the electrified body caused by the body; the current is the electric shock current of the human body. Direct contact with electric shocks is the most serious, and the resulting electric shock current is always far greater than the limit current t
