The nature of the lightning is electricity a phenomenon electricity is a natural phenomenon, is a kind of energy. Electricity is like electrons and protons such subatomic particles produced between the repelling force and attractive one kind of attribute. It is nature's four basic one of interaction. Electricity or charge is of two kinds: we put a positively charged called, another is called become negatively charged. Through the experiment we found a charged object, reactive same-sex attraction, its attraction or follow the coulomb's law repelling force. Electricity is a general term, including many kinds of the existence of because the charge or mobile and produce the phenomenon. This many of them easily observed phenomena, like lightning, static, etc, and some more unfamiliar concept, like electromagnetic field, electromagnetic induction and so on.
Electricity is a natural phenomenon, in ancient people is "lightning" find it through the existing. In ancient China, the ancients believed that electricity phenomenon is Yin qi and sun be the spirit of phase and the generated, "said the word" electricity "solution, Yin and Yang yao, from the rain IP also from" ". The words "have" ray, electricity from back from "by return of Yin and Yang. Thin and into rem, to" for electric discharge and ". In ancient books "on balance" (Lun Heng, about in the first century, namely the eastern han dynasty period) in the book about the static electricity have been recorded, when amber or tortoise the friction, then can attract light small objects, describes with silk friction electric phenomenon, but ancient China for electricity and not too much about. Some 2500 DuoNian before, the ancient greeks found with fur of friction amber to attract some like nap, the straw and so on some light small things, they put this phenomenon known as "electricity". In 1600, British doctor gilbert (1544 ~ 1603) made DuoNian experiment, found the "power", "electricity" and many other phenomenon, attract and the first to use the "power" and "electricity", and other special terms to attract, so many says he is the father of the study of electricity. In the 200 years after gilbert, and a lot of people do DuoCi test, accumulation of the understanding of the phenomena of electricity. In 1734 the French du cut found with th repel each other, different electric power, attract each other phenomenon. 1745, the predecessor of the Prussian (Germany) a vice bishop in the experiment that Chrysler discharges. Of the 18 th century, on the other side of the United States, big electric experts franklin and further revealed DuoCi experiment, the nature of the electricity, and put forward the current this term. He thinks that electricity is a kind of no weight of fluid, exists in all objects in. If the objects are the normal weight than it more electricity, it will be called the positively charged (or "YangDian"); If a body is less than its normal quantity of electricity, it will be called the negatively charged (or "YinDian"). The so-called discharge flow is the process of negative positively charged. Franklin's the statement, in had really can is a way to explain some of the electricity phenomenon, but to understanding the essence of electricity and we now of "two objects friction each other when, easy to move, is the negatively charged electron" view is the opposite. Franklin to another significant contribution to the electricity, is through the 1752 famous kite experiment, "capture TianDian" proof of the sky, and lightning in the electrical ground is one thing. He wire put a big kite in the clouds. The lower end of the wire by a rope, the other in the metal wire hanging on a bunch of keys. When franklin skill pulled, and with the other hand in gently touch keys. So he immediately felt a violent shock (electric shock), also see fingers and key developed between small spark. The experiment results show that: by the rain drenched kite metal line becomes a conductor, the air of charge of the lightning leads to finger between and keys. That was one of the hit event. A year later the franklin created the world's first lightning rod. Current phenomenon of research, for people further research electrical and electromagnetic phenomenon has important significance. The beginning of the current research is Italy's anatomy professor, blessed cut (1737 1798). Blessed cut, from in 1780 found a very common phenomenon of lightning. Lightning make blessed cut the anatomy on the table and indoor tongs and tweezers ring of a frog even contact leg into spasm phenomenon. Strict scientific attitude, that he didn't give up on the "accidental" strange phenomenon of research. He spent the whole time, 12 years of research like frogs legs in the movement of the muscle electrical function. Finally, he found that if the nerve and muscle with two different kinds of metal (such as copper and iron wire) contact, frogs legs will go into spasm. This kind of phenomenon is in a current loop of the produce of the phenomenon. But, to this current blessed cut, the phenomenon of still failed to answer, he reasons that frog leg cramps phenomenon is "animal electricity" performance, the wire loop is just a composed of discharge circuit. Blessed, madame views at the time of the scientific community have resulted in a huge response, but another Italian scientists v play (1745 ~ 1827) don't agree to cut the view, thus he think electric exists in the metal, not is found in muscle, the two kind of obvious different opinions caused the scientific community, and to make the scientific community the debate into two pie. In the spring of 1800, the current debate the causes of further breakthrough. V sent clear of the famous "v playing battery". The battery is composed of a series of round of zinc and silver slice each other and become the emerging devices, in each pair of silver slice and zinc with a kind of between, salt water or other conductive solution at separated from the cardboard. Silver slice and zinc films are two different metal, salt water or other conductive electrolyte solution as, they constitute the current loop. This is a kind of relatively primitive of the battery, composed by many silver zinc cells connected to the battery packs. But at the time, play can invent the battery volts do is very not easy. V playing the invention of the battery so that people first won the can artificially controlled for the future for current, current research of the phenomenon of provides the material foundation for the application of the current effect also opened the prospect, and soon become for electromagnetism and powerful tool for chemical research. 600 BC, the Greek philosopher 'Thales (Thales, 640-' 546-b.c.) know amber friction will attract nap or wood shavings, this phenomenon is called static electricITy). (static And the English language (Electricity) in the old Greek means "amber" (amber). Greek for (elektron), electrostatic produce static there are several phenomenon: (1) contact electric: different material separation have different chemical potential energy, contact produce static. (2) the friction charged (3) dissection of the original material charged: charge balance is broken, both sides take the opposite charge, the same substance to peel and between different materials of the dissection will produce static (4) : the original energy fault zone electric balance is broken lead to two sides opposite electric charge (5) electric conductor of the static electricity transmission by grounding or potential connection can eliminate 6 induction charged: charged body produce electric field, the electric field is the conductor for the charge transfer charged.
自然界的闪电是电的一种现象电是一种自然现象,是一种能量.电是像电子和质子这样的亚原子粒子之间的产生排斥力和吸引力的一种属性.它是自然界四种基本相互作用之一.电或电荷有两种：我们把一种叫做正电、另一种叫做负电.通过实验我们发现带电物体同性相斥、异性相吸,其吸引力或排斥力遵从库仑定律.电是个一般术语,包括了许多种由于电荷的存在或移动而产生的现象.这其中有许多很容易观察到的现象,像闪电、静电等等,还有一些比较生疏的概念,像电磁场、电磁感应等等.
电是自然现象,在古代人们是通过‘闪电’发现它的存在的.在古代中国,古人认为电的现象是阴气与阳气相激而生成的,《说文解字》有“电,阴阳激耀也,从雨从申”.《字汇》有“雷从回,电从申.阴阳以回薄而成雷,以申泄而为电”.在古籍《论衡》(Lun Heng,约公元一世纪,即东汉时期)一书中曾有关于静电的记载,当琥珀或玳瑁经摩擦后,便能吸引轻小物体,也记述了以丝绸摩擦起电的现象,但古代中国对于电并没有太多了解. 　　远在2500多年前,古希腊人就发现用毛皮磨擦过的琥珀能吸引一些像绒毛、麦杆等一些轻小的东西,他们把这种现象称作“电”. 　　公元1600年,英国医生吉尔伯特（1544～1603）做了多年的实验,发现了“电力”,“电吸引”等许多现象,并最先使用了“电力”、“电吸引”等专用术语,因此许多人称他是电学研究之父.在吉尔伯特之后的200年中,又有很多人做过多次试验,不断地积累对电的现象的认识.1734年法国人杜伐发现了同号电相互排斥、异号电相互吸引的现象.1745,普鲁士（德国的前身）的一位副主教克莱斯特在实验中发现了放电现象. 　　18世纪中叶,在大洋彼岸的美国,大电学家富兰克林又做了多次实验,进一步揭示了电的性质,并提出了电流这一术语.他认为电是一种没有重量的流体,存在于所有的物体之中.如果一个物体得到了比它正常的份量更多的电,它就被称之为带正电（或“阳电”）；如果一个物体少于它正常份量的电,它就被称之为带负电（或“阴电”）.所谓放电就是正电流向负电的过程.富兰克林的这一说法,在当时确实能够比较圆满地解释一些电的现象,但对于电的本质的认识与我们现在的“两个物体互相磨擦时,容易移动的恰恰是带负电的电子”的看法却是相反. 　　富兰克林对电学的另一重大贡献,就是通过1752年著名的风筝实验,“捕捉天电”,证明天空的闪电和地面上的电是一回事.他用金属丝把一个很大的风筝放到云层里去.金属丝的下端接了一段绳子,另在金属丝上还挂了一串钥匙.当时富兰克林一手拉住绳子,用另一手轻轻触及钥匙.于是他立即感到一阵猛烈的冲击（电击）,同时还看到手指和钥匙之间产生了小火花.这个实验表明：被雨水湿透了的风筝的金属线变成了导体,把空中闪电的电荷引到手指与钥匙之间.这在当时是一件轰动一时的大事.一年后富兰克林制造出了世界上第一个避雷针. 　　电流现象的研究,对于人们深入研究电学和电磁现象有着重要的意义.最早开始电流研究的是意大利的解剖学教授伽伐尼（1737－1798）.伽伐尼的发现源自于1780年的一次极为普通的闪电现象.闪电使伽伐尼解剖室内桌子上与钳子和镊子环连接触的一只青蛙腿发生痉挛现象.严谨的科学态度,使他没有放弃对这个“偶然”的奇怪现象的研究.他花费了整整12年的时间,研究象青蛙腿这种肌肉运动中的电气作用.最后,他发现如果使神经和肌肉同两种不同的金属（例如铜丝和铁丝）接触,青蛙腿就会发生痉挛.这种现象是在一种电流回路中产生的现象.但是,伽伐尼对这种电流现象的产生原因仍然未能回答,他认为蛙腿的痉挛现象是“动物电”的表现,由金属丝构成的回路只是一个放电回路. 　　伽伐尼的看法在当时的科学界中引起了巨大的反响,但是,另一位意大利科学家伏打（1745～1827）不同意伽伐尼的看法,他认为电存在于金属之中,而不是存在于肌肉中,两种明显不同的意见引起了科学界的争论,并使科学界分成两大派. 　　1800年春季,有关电流起因的争论有了进一步的突破.伏打发明了著名的“伏打电池”.这种电池是由一系列圆形锌片和银片相互交迭而成的装置,在每一对银片和锌片之间,用一种在盐水或其他导电溶液中浸过的纸板隔开.银片和锌片是两种不同的金属,盐水或其他导电溶液作为电解液,它们构成了电流回路.这是一种比较原始的电池,是由很多银锌电池连接而成的电池组.但在当时,伏打能发明这种电池确是很不容易的. 　　伏打电池的发明使人们第一次获得了可以人为控制的持续电流,为今后电流现象的研究提供了物质基础,也为电流效应的应用打开了前景,并很快成为进行电磁学和化学研究的有力工具. 　　西元前600年左右,希腊的哲学家‘泰利斯’（Thales,640-546B.C.）就知道琥珀的摩擦会吸引绒毛或木屑,这种现象称为静电(static electricITy).而英文中的电（Electricity）在古希腊文的意思就是“琥珀”(amber).希腊文的静电为(elektron) ,产生静电有几种现象： ①接触分离电：不同物质有不同的化学势能,接触产生静电.②摩擦带电③剥离带电：物质原有的电荷平衡被打破,两边带上相反的电荷,同种物质的剥离和不同物质间的剥离者会产生静电④断裂带电：原有的能量平衡被打破导致两面相反电荷⑤传导带电导体的静电通过接地或电位连接即可消除⑥感应带电：带电体产生电场,电场中的导体因电荷转移而带电
