These Are The Most Important Electrical Inventions That Changed The World

The discovery of electricity and its eventual harnessing are considered among the most crucial developments in human history. We have put together a list of some of the most important electrical inventions ever. Check out the list below and let us know what you think of it;

The Lightbulb

With the invention of the lightbulb, we were able to banish the night. Before the lightbulb was created, the combustion of different substances was the way to go if you were in need artificial light. This approach was very inefficient and needed a lot of maintenance and care as opposed to lightbulbs. Lightbulbs were also able to light up the streets at night, thus making them much safer.

The Internet

The Internet is one of those electrical inventions that have gone forward to transform the world as we know it. We cannot even consider living without the Internet now. The Internet has shaped how we work, reach out for information, and communicate. The origins of the Internet go back to the 1960s. Since then, it has been steadily growing, and the breakthrough came by Tim Berners-Lee in the late 1980s.

The Alternating Current

AC is also among the most important electrical inventions of all time. It was discovered by Nikola Tesla and has transformed how we look at electricity. Not only was AC safer as opposed to the direct current, but it was also much more efficient over a long distance. A lot of the other entries on this list would not have been possible if it wasn’t for AC.

MP3 Players

You can thank MP3 players for transforming how millions of people would listen to audio files. With their development came the end of an era for CDs and cassette tapes. Their development started during the late 1970s, and they were commercially available and viable during the late 1990s. iPod by Apple was released by Apple in 2001.


Transistors are also among the list of most important electrical inventions ever. Some might even argue that transistors are among the most significant discoveries in the realm of engineering, as well. As per rubberbox.com, ‘Transistors changed the face of technology across the entire planet – without them, we’d have no computers, no smartphones, and only very basic communications (just to name a few). We certainly wouldn’t have any power distribution systems!’

Global Positioning Systems

GPS was conceived as a top-secret military project during the 1960s. However, it has helped transform the way we navigate on Earth. Back in 1995, the system was completely functional thanks to the efforts of three men; Roger L. Easton, Ivan A. Getting, and Bradford Parkinson.

Digital Cameras

The very first electronic digital camera was developed back in 1975by Eastman Kodak’s Steven Sasson. It was originally intended for scientific and later on military purposes. However, by the mid to late 90s, digital cameras had become quite common among consumers.

Electric Cars

You’d be surprised to know that electric cars have been in the making for quite some time. In fact, the earliest models date back to the late 1880s. However, those models were left far behind after the development of internal combustion-engine vehicles skyrocketed.

Electric Motor – The defining invention of electrical inventions!

Electrical motors are also hailed as one of the most important electrical inventions of all time. They are capable of transforming electrical energy into mechanical energy and have helped transform a vast majority of industries forever!
