電気工学は私たちの生活に欠かせない分野の一つです。歴史的な観点から見ると、多くの発明家、科学者、エンジニアがこの分野に貢献してきました。この記事では、電気工学の歴史で最も重要な10人の人物を紹介します。まずはじめに、静電気から電気工学へと。現代の電気工学は17世紀に始まりました。

1582年、ウィリアム・ギルバートが『デ・マグネテ』を出版し、それは電磁気学の重要な業績であり、電気工学の発展に道を開きました。1660年、オランダの物理学者ロバート・ファン・デ・グラフが、静電気の研究を大きく進歩させるファン・デ・グラフ発電機を発明しました。また、1731年、フランスの科学者シャルル・クロームが、静電気が物体間に作用する力であることを示す論文を発表しました。これにより、電気工学の基本原理が明らかになりました。18世紀初頭、アメリカの哲学者ベンジャミン・フランクリンはカイトと鍵の実験を行い、正と負の電荷が存在することを示しました。

フランクリンは、暖房の配信を効率的に行うことが可能なフランクリンストーブを発明しました。また、避雷針の実験に参加して、静電気学の理論に大きな貢献をしたとされています。1752年には、軽い金属板と帆布袋をカイトに結びつけ、雷を誘導してそれに接近することで電気の存在を証明する実験を行いました。彼の発見は計り知れず、現代の電気工学の基盤を築きました。

電気が私たちの生活に深く浸透し、多くの発見がなされました。この記事では、ohm、faraday、ampereの重要性に焦点を当てることにします。オームの法則、ファラデーの法則、およびアンペアの法則は、現代の電気工学の基礎を築いたと言えます。ジョージ・サイモン・オームは、電流と電圧の関係を発見し、電気の流れに関する法則を定式化しました。これらの法則は、電気回路の設計に欠かせなく、今でも使用されています。一方、マイケル・ファラデーとアンドレ・マリー・アンペールは、電磁誘導現象を発見しました。ファラデーは、回転する磁場が導体に電流を誘導することを示し、一方アンペールは、電流が磁場を作り出すことを実験的に証明しました。これらの法則は、電気エネルギーを変換する多くの装置で使用され、電気工学の発展に大きく貢献しています。電磁誘導は、情報をリモートで送信するために無線通信にも使用されています。ohm、faraday、ampereによるこの発見のおかげで、現代の通信技術とエネルギー産業は維持されています。

電磁気について学ぶ上で必要なのは、マクスウェルの方程式です。彼は従来まとめられていなかったファラデーの法則、クーロンの法則、オームの法則など、多様な電気基礎を開発し、液体力学に誤差補正項を加えるなど、完全に新しい範囲に発展させました。彼の業績は電磁波、偏光、電磁場などの概念を明らかにし、現代の情報技術の基盤に不可欠です。

エジソンとウェストンの名前は、全ての電気機器の基盤である直流発電、商用発電所、白熱電球、電気椅子などに関連しています。彼らは、19世紀および20世紀初頭に、DC（直流）を開発し、その限界を実験して最初の商用発電所を建設しました。一方で、白熱電球や電気椅子は私たちの日常の必需品になりました。彼らの発想は欠陥があったかもしれませんが、その限界を探求して自らの手で発展を遂げました。また、彼らはエンジニアとして働くだけでなく、マーケティングにも力を入れました。彼らはトレンディな製品や新しい技術を宣伝するのに熟練していました。彼らの業績は今日当然のように受け入れられていますが、私たちが今日享受している電気は彼らの研究開発の成果から生まれたものです。彼らの貢献を忘れるわけにはいきません。

ニコラ・テスラとジョージ・ウェスティングハウスは、交流電力伝送の現代的な利用の基礎を築きました。テスラは特に効率的に電力を伝送する方法を研究し、彼の名前を冠したテスラコイルは高周波電力を効率的に伝送する手段として今も研究されています。彼らの貢献により、電力はより効率的かつ安価になり、より多くの人々がそれを使用することができるようになりました。彼らの発明は、私たちが快適に暮らすことを可能にしました。また、テスラは無線通信の分野でも重要な貢献をし、彼の発明により、世界中の人々が情報をやり取りすることができるようになりました。彼は物理学の分野でも重要な発明をしました。テスラによって発明された重要な装置であるマグネトロードは、今でも多くの科学者によって研究されています。彼らの功績は現代の科学技術の必須部分であり、私たちの生活に大きな影響を与えています。交流電力伝送、テスラコイル、無線通信、マグネトロード。これらの発明は私たちの生活に大きく貢献し、今なお彼らの功績を称えています。

Introduction

Electrical engineering is one of the indispensable fields in our lives. From a historical perspective, many inventors, scientists and engineers have contributed to this field. In this article, we will introduce the 10 most important figures in the history of electrical engineering. Now, let’s begin.

From Static Electricity to Electrical Engineering

Before I start my talk, may I ask if any of you have ever experienced static electricity? Yes, that feeling when you rub a blanket and it makes a crackling sound. Humans didn’t suddenly start studying electrical engineering. Its origins can be traced back thousands of years, to the time of the Roman Empire. However, modern electrical engineering began in the 17th century. After centuries of trial and error, several key inventions were made.

In 1582, William Gilbert published De Magnete, a seminal work on electromagnetism, which paved the way for electrical engineering. In 1660, Dutch physicist Robert van de Graaff invented the Van de Graaff generator, which greatly advanced the study of static electricity. In 1731, French scientist Charles Coulomb published a paper on electricity, which revealed that static electricity is a force that acts between objects.

From this discussion, the basic principles for the development of electrical engineering became clear. In the early 18th century, American philosopher Benjamin Franklin conducted the kite and key experiment, demonstrating the existence of positive and negative charges.

Benjamin Franklin

Benjamin Franklin is one of the most notable figures. Franklin was the most talented and influential inventor among many inventors. He invented the Franklin stove, which made it possible to efficiently deliver heat. He also participated in experiments with lightning rods and made a significant contribution to the theory of electrostatics. In 1752, Franklin tied a light metal plate and a canvas bag to a kite and induced lightning by approaching it to the clouds. This experiment proved the existence of electricity in the clouds and reaffirmed the importance of electrostatics theory. Franklin’s contribution was immeasurable, and his discoveries laid the foundation for modern electrical engineering. Anyway, what about the idea of flying a kite into a thundercloud? Well, let's pay tribute to his great achievement first.

Ohm, Faraday, Ampere

Electricity has deeply penetrated our lives and many discoveries have been made. In this article, we are introducing important figures in the history of electricity. In the previous article, we saw the evolution from static electricity to electricity. This time, let’s focus on Ohm, Faraday, and Ampere.

Ohm’s Law, Faraday’s Law, and Ampere’s Law can be said to have laid the foundation of modern electricity. Georg Simon Ohm discovered the relationship between current and voltage and formulated laws regarding the flow of electricity. These laws became indispensable in the design of electrical circuits and are still used today.

On the other hand, Michael Faraday and Andre Marie Ampere discovered electromagnetic induction phenomena. Faraday demonstrated that a rotating magnetic field induces a current in a conductor, while Ampere experimentally demonstrated that a current creates a magnetic field. These laws are used in many devices that convert electrical energy, greatly contributing to the development of electrical engineering.

Electromagnetic induction is also used in wireless communication to transmit information remotely. Thanks to the discoveries of Ohm, Faraday, and Ampere, modern communication technology and the energy industry are sustained.

However, these discoveries were not made easily. In fact, when Ohm first announced his law, no one understood it. Similarly, Faraday conducted experiments for many years to prove the importance of his discovery. And Ampere performed experiments publicly to change people’s thinking.

In recognition of these achievements, the units of electrical measurement, the ohm, faraday, and ampere, are named after Ohm, Faraday, and Ampere, respectively. Their achievements are remarkable in the history of science and will continue to be indispensable for the development of electricity.

Maxwell’s equations

What is essential for us to learn about electromagnetism is Maxwell’s systematized Maxwell’s equations. He developed a variety of electrical basics such as Faraday’s law, Coulomb’s law, and Ohm’s law, which had not been previously compiled, and expanded his accomplishments into a completely new range, such as adding error correction terms in fluid mechanics. His accomplishments led to the elucidation of concepts such as electromagnetic waves, polarization, and electromagnetic fields, and are crucial to the foundation of modern information technology. His accomplishments are truly worthy of admiration.

Edison, Thomas Weston

The names of Edison and Weston are synonymous with the foundation of all electrical equipment - from incandescent light bulbs to the electric chair, from the first commercial power plants to the limits of DC power transmission. Throughout the 19th and early 20th centuries, they developed DC (direct current) and constructed the first commercial power plant to test its limits. Meanwhile, incandescent light bulbs and electric chairs became essential parts of our daily lives.

It is noteworthy that their concept of DC was flawed; nonetheless, they explored its limits and achieved further development with their own hands. Additionally, they not only worked as engineers, but also helped with marketing. As expected, they were well-versed in promoting trendy products and new technologies.

Today, their achievements are taken for granted. However, all the electricity we enjoy today originates from their research and development. We cannot blatantly forget their contributions.

Nikola Tesla, George Westinghouse

Nikola Tesla and George Westinghouse laid the foundation for the modern use of alternating current power transmission through their contributions. Tesla particularly explored ways to transmit electricity efficiently, and among his inventions is the Tesla coil, named after him, which is still studied today as a means of efficiently transmitting high-frequency electricity.

Thanks to their contributions, electricity has become more efficient and inexpensive, allowing more people to use it. Their inventions have enabled us to live comfortably. Tesla also made important contributions in the field of wireless communication, allowing people to exchange information around the world with his inventions. He also made important inventions in the field of physics. Magnetrode, an important device invented by Tesla, is still studied by many scientists today.

Their legacy is an essential part of modern science and technology and has had a significant impact on our lives. Alternating current power transmission, Tesla coil, wireless communication and magnetrode. These inventions have contributed greatly to our lives, and we still honour their achievements today.

Conclusion

The important figures in the history of electrical engineering have played an indispensable role in the development of modern electronics. Over the approximately 500-year history from static electricity to modern electromagnetism, many discoveries and inventions have been made. The achievements of Gilbert, Van de Graaff, Coulomb, Franklin, Ohm, Faraday, Ampere, Maxwell, Edison, Thomas Weston, Nikola Tesla, George Westinghouse, and others continue to affect our lives today. In tribute to their great achievements, their inventions and discoveries still have a profound impact on us today.
