When the bird stands on the high-voltage line, the two legs of the bird are equivalent to being connected in parallel on the conductor. Because the bird is too small and the distance between the two legs is very close, the voltage difference borne by the bird is very small, and the current flowing through its body is very small, which is not enough to cause harm to the bird. Why can birds stand on high-voltage lines? The premise of electric shock is to generate a certain current. There must be a complete circuit to generate current, which includes live wire, zero wire and conductor.
There is a layer of cuticle on the bird's feet, which has the function of insulation.
If the bird touches the live wire and the zero wire at the same time, it will be electrocuted. （DiaoWeiShenMeKeYiZhanZaiGaoYaXianShang?）
