有些电视机接通电源后,用手接触电视机天线时会麻手,这是电视机天线上的漏电流及感应电荷通过人体对大地放电造成的。不过这种电流很微弱,一般不会伤人。电视机天线为什么会有电呢?这是因为电视机天线与电视机金属底盘有感应电流。金属底盘和天线都是导体,手接触天线后引起放电就会感到麻手了。人体绝缘电阻不相同,对微弱电流的感觉也不一样。一般人只有在手比较潮湿、不穿绝缘鞋时,才会有比较明显的感觉;极少
Some TV sets turn on the power and touch the TV antenna by hand. This is the leakage current on the TV antenna and the induced charge is discharged through the human body to the earth. However, this current is very weak, generally not hurt. Why does the TV antenna have electricity? This is because the TV antenna and television metal chassis have induction current. The metal chassis and the antenna are all conductors, and when the hand touches the antenna, it will feel awkward. Human insulation resistance is not the same, the feeling of weak current is not the same. Most people only in the hands of more humid, not wearing insulated shoes, there will be more obvious feeling; very few
