Electricity: 2. How electricity is used

I understand what electricity is, but I don't understand how it's used.

So, let's think together about how electricity is used in our daily lives!

In this issue, we would like to introduce how electricity is actually used for such people.

Please read this article to the end, as it will give you a better understanding of electrical energy conversion and allow you to enjoy electronic construction more.

Use of Electricity

This is still not enough to help you with what we have described so far, since electricity is just a flow of electricity.

Use of Electricity

Electricity has become so indispensable to us because of its property of being easily converted into other forms of energy.

The following image is an example of how electrical energy is converted into energy for use.

What kind of energy is electrical energy converted into and used for?

This alone should give you an idea of how electricity is applied in many different areas!

Whether the product is very old or very new, what it is basically doing is this energy conversion, and the essence of the process has not changed.

Latest Gadgets and Energy Conversion

For example, the VR goggles in the image below convert electrical energy into light energy to illuminate the LCD backlight.

Next, drones use electrical energy to turn motors and convert it into kinetic energy called buoyancy, which allows them to float in the sky.

The servo motors used in this work also fall under this use of kinetic energy.

These are just a few examples, but I hope you can see how electrical energy is used in many different areas.


In this article, we have introduced the uses of electricity for those who do not understand how electricity is used.

Now that you have a deeper understanding of electricity and can enjoy electronic construction even more, we hope you will try your hand at a variety of challenges.

This site also provides other videos and articles to help beginners learn electronics construction systematically from zero, including explanations of the minimum knowledge and tools they need to acquire.

We also have an article that explains the basics of what electricity is, so please take a look at that as well!
