The importance of safe use of electricity:
In the 2 1 century, electricity is everywhere in our lives. As an energy source, electricity is used and popularized by us, which is closely related to people's lives and the operation of equipment. However, there are always two sides to one thing. While electricity benefits mankind, there are also many hidden dangers, and improper use of electricity will cause disaster.
For example, when current passes through the human body (so-called electric shock), it will do harm to the human body, generally speaking, it will destroy the normal work of the human heart, respiratory system and nervous system, and even endanger people's lives in serious cases.
When electrical equipment breaks down, sometimes it will not only damage the electrical equipment, but also often because it is on fire. Therefore, when we use electricity, we should not only improve our understanding of ideas, but also prevent its negative effects.
