[Reporter Xie Jieyu/Report from Nantou] "Heating?" With the arrival of the first wave of cold in winter, the temperature in Taiwan plummeted. From time to time, flocks of sparrows can be seen huddling together in the open fields and telephone poles in Nantou County, attracting the attention of people passing by. I can't help but ask, are sparrows also afraid of the cold? They nest together densely to keep warm and charge? But why don't they get an electric shock? Many people are puzzled and curious!

The Agriculture Department of Nantou County Government stated that sparrows are birds that live in groups, especially in the cold winter, not only on utility poles, but sometimes groups of sparrows can also be seen on tree branches, because sparrows on the wires give people a visual impact The force is too great, so everyone will be particularly impressed.

Please read on...

In fact, the purpose of sparrows standing on wires or branches is the same. It is to keep warm and find food, and to defend against enemies together. As the saying goes: "United strength is great", if the sparrows flock together, the chances of survival will be relatively higher.

However, warning signs of "High voltage danger! Do not approach!" are often seen on high-voltage power lines. Online condescending search for prey for food?

The reason is also of concern to all walks of life.

According to Taipower Company, generally high-voltage wires are divided into several wires, one of which has a voltage of 0v, which is what the general public calls the "ground wire", and the others are all voltage-existing, so-called "fire wires."

Whether a sparrow gets an electric shock has nothing to do with its size, but its two feet stand on the same wire, so the voltage of the two feet is the same high, and there will be no current if there is no potential difference (voltage difference). If you step on different wires, you may get an electric shock and turn into a bird, which also highlights the clever side of the sparrow.

With the arrival of the cold snap, flocks of sparrows can be seen swarming on the electric poles in various places in Nantou County from time to time. Why didn’t they get electrocuted?

It also attracted attention from the outside world.
