When the current of about 1 mA passes through the human body, it will produce uncomfortable feelings such as tingling. When the current of 10~30 mA passes through the human body, it will cause paralysis, severe pain, spasm, hypertension, dyspnea and other symptoms, but it is usually not life-threatening; If the current reaches more than 50 mA, it will cause ventricular fibrillation, which is life-threatening; The current above 100 mA is enough to kill people.
