Why wouldn't the bird be electrocuted standing on the wire?
小鸟站在电线上为什么不会触电?
The key is that the bird is small, and the two feet are standing on the same wire.
关键是小鸟它很小,两脚站在同一根电线上;
Birds and wires are formed in parallel,
小鸟和电线形成并联,
and the current of the bird's body is very small and does not touch electricity.
通过小鸟身体的电流很小,不致触电。
This is the principle of a man's live work.
人的带电作业也是这个原理。
But if the bird stood on the wire and pecked against the tower, it would be fatal.
但如果小鸟站在电线上又去啄碰铁塔,那就是致命一啄了。
It will die because of electricity and short circuit.
