【Physical electric battery】Ⅱ

A road sign which turns on a light at night.It generates electricity with a solar battery and the electricity which was stored in a battery is used for the road sign💡

When connecting two kinds of metals and heating the one,an electric current runs between the metals.We call it what is called ｾﾞｰﾍﾞｯｸ効果🙋

We can't get high voltage with only a pair of metals,butwe can change it into an electric battery of high voltage by accumulating lots of metals or making use of difference between temperature.👍

When electric current runs into the battery,one end of the metal absorbs heat and the other end release the heat. We call it ﾍﾟﾙﾁｪ効果 and we call the device ﾍﾟﾙﾁｪ素子.😃

The ﾍﾟﾙﾁｪ素子 is adopted for a portable fridge or a cooling device inside of a computer.Incorporateing the ﾍﾟﾙﾁｪ素子 into small parts which give off heat such as semiconductor or IC can drop temperature.🙋
