5 Ways electrical engineering changed the world

Rate this Entry
There are a number of fields that have changed the world we live in today. These different fields have achieved a lot of different advancements however, few have achieved as much as electrical engineering has.

Electrical engineering is a complex field that studies electricity and electronics. A lot of electrical engineering is what we call mature technology which means it needs to branch into new electronics and new physics to produce massive changes within society. The importance of electrical engineering is very high; it has been a huge part of our developing society. Let�s take a look at 5 achievements electrical engineering has achieved over time.

1.Solar energy
Solar energy is now used for a number of things including solar powered heating, thermal energy, solar architecture and artificial photosynthesis. It is an important source of renewable energy and is one of the most appealing sources of electricity. A huge number of the population is saving money and power by investing in fixed and portable solar panels which have huge long term benefits.

In 2011, the International Energy Agency said that "the development of affordable, inexhaustible and clean solar energy technologies will have huge longer-term benefits. It will increase countries� energy security through reliance on an indigenous, inexhaustible and mostly import-independent resource, enhance sustainability, reduce pollution, lower the costs of mitigating global warming, and keep fossil fuel prices lower than otherwise. These advantages are global. Hence the additional costs of the incentives for early deployment should be considered learning investments; they must be wisely spent and need to be widely shared.

2. Insulators
Insulators or insulation was invented to keep things like electricity, the heat and the cold from easily escaping. An electrical insulator is a material whose electrical charges do not flow freely; things like wood, plastic, rubber and glass are good insulators. The first person to ever use insulation is not known however, the history of insulation goes back to the very early days of humanity. Prehistoric man built shelters with materials to protect them from the weather and other conditions, similar to our modern day insulation. Without insulation any heating, cooling or energy would escape the room.

3. The battery
An electric battery consists of one or more electrochemical cells with external connections provided to power electrical devices. The most used battery is the primary battery which is used once and then disposed of. They are commonly used for flash lights and other portable devices. While important they are secondary to rechargeable batteries which can be recharged multiple times. They come in all shapes and sizes to power a multitude of devices including wristwatches, remotes, hearing aids, toys and so on. They have changed and enhance a way of life.

4. Radio Broadcast
This history of radio dates back to 1830s when radio development began as wireless telegraphy. James Clerk Maxwell showed in theoretical and mathematical form in 1864 that electromagnetic waves could propagate through free space. Radio has transformed society and was what gave birth to the entire field of electronics. At first no one thought radio was very promising in a world dominated by telegraph and telephone. However radio has now become a part of everyday lives, we rely on it to listen to sports, the news, music and other current events.

The telephone is a multipurpose tool that has changed our society for the better. It has come a long way and is now used in the home, business and within education as a source of communication, entertainment and for academics. When it was first introduced in 1876 by Alexander Graham Bell, only the rich could afford to buy it. However, things have changed and a multitude of people have access to the telephone. They come in all shapes, sizes and vary in price. The telephone has changed the way we communicate as well as our social relationships. The telephone makes it possible to stay in contact with long distance relationships, enabling us to maintain a strong bond with our family and friends.

    It's so cool when students have enough free time for such activities! I myself don't because I have lots of college papers to complete. I'm even thinking of buying some of them. Is it a good idea in your opinion? Anyway, what these students do is awesome. Hopefully, someday when I'll be relatively free I'll participate in something like that.

    Incomplete or pending assignments are some common issues faced by scholars. When you are busy with many activities, you can’t get enough time for writing your assignments or homework. For writing assignments, you have to manage your time and handle other things as well. Writing academic papers or research work needs to frame all information properly and correctly. Many things need to keep in mind when you are composing your academic papers such as grammar, referencing style, structuring, etc. if you have any loopholes, you will not get the right output. In this situation, you can buy finance assignment online across the globe.

    Hello, I agree with you that's for sure. Engineering plays a crucial role today. A few days ago I read one article which was written by outline writing service where similar aspects of engineering were discussed.

    Everytime I read about Alexander Bell and how his invention changed the world, I feel that evolution of technology nowadays becomes more rapid and less shocking with each year (Except for my school teacher. Bless his old soul, he blamed everything wrong with students (them being late to class or completely absent) on "these stupid gadgets"). Alexander' Bell's invention was a miracle, but in our time, if someone creates some new technology, it will be met with a shrug and jokes like "But what about cancer cure?".
