The origin of electricity

As we all know, Edison invented the tungsten light bulb, which extended the time of light bulb, so who invented electricity?

Between 1749 and 1751, Benjamin Franklin carefully observed and studied the formation of thunder, lightning, and clouds, and hypothesized that lightning in clouds and friction produced the same electrical properties. In 1752, he made a world-shaking experiment with electric kites in Philadelphia: under the condition of lightning, the kite collected atmospheric electricity into a Leiden bottle to charge it, thus proving his assumption of "the identity of lightning and static electricity".

Franklin's contribution to physics was mainly in the field of electricity. He unified the chaotic knowledge of electricity at that time and systematically expounded the theories explaining various electrical phenomena (such as the generation of charge, the transfer of charge, electrostatic induction, etc.). He made remarkable achievements in the exploration of "electricity". In order to explore the law of electric motion in depth, many special terms such as positive charge, negative charge, conductive body, battery, charge, discharge and so on have become universal words in the world. Due to the invention of electricity, there have been many casualties and accidents, so our company has invented intelligent communication products between people and electricity again and again, so that more people can avoid the harm caused by electricity, YINTE - synonymous with safety is our constant mission.

A simple understanding of the origin of "electricity", then let me give you a brief introduction to our company once again to create the design of multi-functional replaceable head digital display measuring pen, there are also a lot of innovative functions oh!

Product introduction
