The History of Electrical Engineering

By

必威体育网页登录在当今迅速推进技术的世界中,电气工程师在当今的迅速推进的世界中致残。他们是设计,开发和测试电气设备和系统的任务。从智能手机到超级计算机,电气工程师深入参与了工程过程的每一步。必威体育网页登录但是电气工程是什么?必威体育网页登录

The definition of electrical engineering is different depending on who you ask. Electrical engineers would agree that it is the branch of engineering that deals with the technology of electricity, of course, but it is so much more than that. On a fundamental level, electrical engineers combine the physics and mathematics of electricity, electromagnetism, and electronics and apply them to information processing and energy transmission.

The discipline of electrical engineering is young—less than 200 years old—but rapid advances have been made in such a short time. Developments are being made so quickly that what some considered to be years away have become reality, giving electrical engineering a fascinating history. How the discipline has evolved into what it is today may shock you.

要了解电气工程史,请先看电力历史。必威体育网页登录然而,人类的电力起源的记录充其量不足。例如,人类知道电鳗和闪电,但是如何产生电力。虽然电力历史充满了未知数,但大多数人都同意英国化学家和物理学家Michael Faraday,占据了一大堆建立电气工程作为学习领域。必威体育网页登录

电气工程之父:迈克尔·法拉第必威体育网页登录

出生于1791年的迈克尔·法拉第没有接受过传统的科学教育。他成了一个装订工的学徒,在那里他从装订的书中学到了科学知识。当他对科学产生兴趣时,他开始参加科学讲座。他对电学、电学和力学特别感兴趣。最终,他参加了汉弗莱·戴维的四次讲座,这标志着他科学生涯的开始。

1814年,法拉第与戴维在欧洲各地旅行了18个月,会见了许多科学家,并一路发展他的科学知识。回国后,他与戴维一起做了几年化学实验,直到1821年他发表了关于电磁旋转的研究,这是电动机的原理。这一刻,也许是电气工程学科的诞生。必威体育网页登录

在法拉第完成电力的重大工作较长,花了十年。1831年,他发现了电磁感应,这是电动变压器和发电机后面的原理。他证明磁铁可以在电线中诱导电流,在那里他将机械能转化为电能。必威体育网页登录这次发现表明,电力具有巨大的技术发展潜力。它不必局限于实验室。

法拉第于1867年去世,为电力世界做了很多贡献。他的工作是电气工程的基础,因为他发现的基本原则今天仍在使用中。必威体育网页登录

Recognizing electrical engineering as a field of study

虽然电力研究最初被认为是物理学的一部分,但电气工程最终分支为自己的纪律。必威体育网页登录1883年,世界上第一位电气工程学院成立于ThepischeUnivers必威体育网页登录itätdarmstadt。其他学校遵循适合向崭露头角的电气工程师提供教育,而该领域继续扩大。必威体育网页登录

Since electricity was becoming increasingly influential in society, an organization to support those in electrical professions was formed in 1884. This organization was known as the American Institute of Electrical Engineers. In 1963, this organization merged with the Institute of Radio Engineers (formed in 1912) to form the Institute of Electrical and Electronics Engineers, which today is the world’s largest technical professional organization.

电气工程进步必威体育网页登录

自从电气工程学院在达姆施塔特建立以来,电气工程取得了巨大进步。必威体育网页登录从那时起,雷达,智能手机和计算机都被发明了。法拉第会惊讶!

电子技术也有了巨大的进步,比如电视。20世纪20年代发明电视机时,电视机屏幕很小,只能黑白显示图像,只有富人才能买得起。今天,电视屏幕是巨大的。它们可以以惊人的分辨率显示丰富的颜色,而且比以往任何时候都更实惠。

电气工程史必威体育网页登录电气工程的其他主要进步包括Wi-Fi,激光器,微波炉和智必威体育网页登录能家居产品。必威体育网页登录由于法拉第的时间,电气工程已经走了很长的路!

世界今天会尽可能地停止运作,没有电气工程师。必威体育网页登录全球定位系统是他们贡献的一个很好的例子。必威体育网页登录电气工程师有助于开发这些系统的组件,使它们能够承受多年的使用。如果没有他们的贡献,您的智​​能手机就不知道您的位置,您无法跟踪亚马逊包的位置。下次使用电子设备时,请务必感谢电气工程师。必威体育网页登录

Recent innovations in electrical engineering

Electrical engineering is a constantly evolving field, and continues to produce incredibly innovative products. Being able to check the contents of a refrigerator while on vacation? Boots that can provide workers with alerts of unsafe environmental conditions? Having food delivered by drone? What were dreams a decade ago are now realities.

这些纪律将继续以Breakneck节奏发展。处理电源将继续提高,允许生产更小,更快,更具创新的设备。摩尔定律,其指出,可以每两年将微芯片加倍的晶体管数量兼容,允许处理能力以指数增长。在20世纪70年代中可能举办少于100,000个晶体管的微芯片今天举办超过500亿。

The future of electrical engineering

在一个日益technological world, electrical engineers are more in demand than ever. They will be called upon to provide innovative engineering solutions for diverse industries, such as telecommunications, automobile, and renewable energy. Luckily, electrical engineers are more than up to the challenge!
