An Introduction To Electrical Power And Energy Why Do You Need To Know About Electrical Energy? What Is Electrical Power? Power and Energy In Electrical Devices Resistors Batteries ProblemsYou are at: Basic Concepts - Quantities - Power & Energy Return to Table of Contents --------------------------------------------------------------------------------Why Do You Need To Know About Electrical Energy? A power station is a place where other forms of energy - coal, gas, potential energy in water and nuclear energy - are turned into electrical energy for transmission to places that use electrical energy. Electrical engineering is concerned with transmission and ultilization of two things - energy and information. Here, in this lesson, we are going to focus on power and energy. In this lesson you will want to learn the following. Given an electrical circuit or device Be able to compute instantaneous rate of energy use (power). Be able to compute how much energy is used over a period of time. Be able to compute how much energy is stored in an electrical storage device like a battery or a capacitor.--------------------------------------------------------------------------------What Is Electrical Power? Electrical power is conceptually simple. Consider a device that has a voltage across it and a current flowing through it. That situation is shown in the diagram at the right. The voltage across the device is a measure of the energy - in joules - that a unit charge - one couloumb - will dissipate when it flows through the device. (Click here to go to the lesson on voltage if you want to review.) If the device is a resistor, then the energy will appear as heat energy in the resistor. If the device is a battery, then the energy will be stored in the battery. The current is the number of couloumbs that flows through the device in one second.j (Click here to go to the lesson on current if you want to review.) If each couloumb dissipates V joules, and I couloumbs flows in one second, then the rate of energy dissipation is the product, VI. That's what power is - the rate at which energy is expended. The rest of the story includes these points. It doesn't matter what the electrical device is, the rate at which energy is delivered to the device is VI as long as the voltage and current are defined as shown. The power can be negative. If the device is a battery, then current - as defined in the figure - can easily be negative if, for example, a resistor is attached to the battery. If the power is negative, then the rate at which the device expends energy is negative. That really means that it is delivering energy in that situation. --------------------------------------------------------------------------------Power in Electrical Devices A resistor is one device for which you can compute power dissipation. A symbol for a resistor is shown below, along with a voltage, Vr, across the resistor and a current, Ir, flowing through the resistor. We can compute the power delivered to the resistor. It's just the product of the voltage across the resistor and the current through the resistor, VrIr. But there's more to the story. In a resistor, there is a relationship between the voltage and the current, and we can use that knowledge to get a different expression - one that will give more insight. We know that Vr = Rir, so the power is just: Power into the resistor = VrIr = (RIr)Ir = R(Ir)2. We can also use the expression for the current Ir = Vr/R, Power into the resistor = VrIr = Vr(Vr/R) = (Vr)2/R. At different times, these two results - which are equivalent - can be used - whichever is appropriate. Besides being a useful result tthese are also illuminating results (And that's not a reference to the fact that a typical light bulb is a resistor that dissipates power/energy.). The power dissipated by a resistor is always positive. That means that it does not (and in fact it could not) generate energy. It always dissipates energy - uses it up - contributing to the heat death of the universe. We know the power is positive because R is always positive (and it will always be for any resistor that doesn't have hidden transistors) and because the square of the current has to be a positive number. --------------------------------------------------------------------------------Problems P1. You have a 1KW resistor, and there is 25 volts across the resistor. Determine the power (in watts) that the resistor dissipates.

Your grade is:--------------------------------------------------------------------------------Power In Batteries Batteries are ubiquitous components. They are in TV remotes, cell phones and things like that. But, batteries also appear in places you don't expect them to be. For example, you can turn this computer off. When you turn it back on it remembers things and recalculates things like the time. Now, you expect that for things that can be stored on a hard drive. You don't expect it for the time. When you turn this computer off and later turn it back on it will have the right date and time. How does it do that? If you think about it (and don't do that for too long!) you have to believe that there is a battery somewhere inside the computer and that when you turn the computer off that battery runs some sort of little clock hidden inside the computer. You can't see the clock and you wouldn't even know it's there, but you can probably see the time now on the task bar of this computer - and it's probably close to being right! Batteries are used to solve many problems. They are used to provide power to run things like computer clocks that need to keep running even in the absence of AC power. They are used to store energy for things like starting a car. When you run the car you generate energy (from the gasoline) and store it in the car battery. Then there is energy there when you need it to get the car going again. They are used for low power devices to make them portable. That includes things like cell phones, TV remotes and calculators. You use batteries - whether you want to or not, and whether you know it or not! You need to be able to compute some of the quantities involved. Here is a simple circuit where a resistor is connected to a battery. We know some salient facts about this circuit. There is energy stored in the battery and the battery delivers stored energy to the resistor. The resistor dissipates energy, and what happens physically is that the electrical energy that is delivered to the resistor gets turned into heat energy and the resistor becomes warmer. Now, we need to look at a circuit diagram for this situation. That circuit diagram is shown to the right of the picture below. In the diagram, we have defined a battery voltage, Vb, and a current, Ir. Notice that we have used a natural definition for the current polarity. We have the arrow pointing out of the battery and into the resistor. We do that because we know that positive charge actually flows from the battery terminal through the resistor. That definition of current polarity raises questions about calculation of power to/from the battery. Let us consider the power flow into the battery. Power flow into the battery or any other device - is the product, VI, when V is the voltage across the device, and I is the current flowing into the device. Remember, for our polarity conventions here, the current arrow points into the terminal of the device that is labelled "+" for the voltage definition. We have reproduced the diagram from above here to emphasize how the voltage and current polarities are defined. Notice that the current arrow in our earlier definition points toward the "+" sign on the device. In the battery-resistor circuit below, the current arrow is directed out of the positive ("+") terminal of the battery. That means the power delivered to the battery must be computed by (note the minus sign!): P = - VIWhat does this mean? Let's look at a numerical example. Let's assume the battery voltage is 12 volts and the resistor is 24 ohms. That means the current is 0.5 amps, i.e.: Ir = 12v/24W = 0.5aIn other words, the power flowing into the battery is: P = - Vb Ir = - 12 * 0.5 = - 6wThe power flowing into the battery is negative! The power flowing out of the battery is positive! And, it makes sense because we know the battery supplies power. How much energy is stored in a battery? Batteries are often rated in ampere-hours (or milliampere-hours) and an ampere-hour is really a unit of charge. As a battery is used it discharges - charge flows from the battery - but it tends to hold a constant voltage. This is different than the internal resistance of the battery. What we are saying here is that as time goes on - for the same current drawn from the battery - the voltage stays about the same. There may be a slight drop-off but it is not very large. Thus, if we have a 12.6 v battery, it will have something close to 12.6v until it gets close to being discharged. Let's say we have a 12.6v battery rated at 70 ampere-hours. Assuming it can deliver 1 ampere for 70 hours, then it will be delivering Power = 12.6v x 1.0 amp = 12.6 watts for 70 hours. That works out to 12.6 x 70 = 882 watt hours or .882 kw-hr. - and remember you pay the electric company by the kilowatt-hour! In joules we have 882 w-hr x 3600sec/hr = 3,175,200 joules. That might sound like a lot, but an interested student might want to compare that amount of energy with the energy stored in a gallon of gasoline.

《海外英语》、《英语广场》等期刊可以发表英语学术论文。
从广义上来讲，期刊的分类，可以分为非正式期刊和正式期刊两种。非正式期刊是指通过行政部门审核领取“内部报刊准印证”作为行业内部交流的期刊，但也是合法期刊的一种，一般正式期刊都经历过非正式期刊过程。
正式期刊是由国家新闻出版署与国家科委在商定的数额内审批，并编入“国内统一刊号”，办刊申请比较严格，要有一定的办刊实力，正式期刊有独立的办刊方针。
了解核心期刊具有重要的意义。就编者而言，可以从核心期刊吸取经验。就读者而言，树立核心期刊意识，可以明确价值取向，提高阅读档次。
就图书馆而言，在经费有限的情况下，订阅时当然是以核心期刊为首选目标。就科研管理部门而言，可以统计分析单位或个人在核心期刊上发表论文的情况，以此作为衡量其学术水平的一项重要指标。
谈英文学术论文发表和写作技巧 最近，国内几个同行和我谈及用英文发表学术论文的问题，我想借这个地方谈谈我的经验和看法。国内语言学和应用语言学的学者倾向于在国内用中文发表文章，主要是因为， 一来, 学校要求老师和研究生在核心期刊上发文章；二来，英文毕竟不是母语, 写一篇英文文章的时间可以用来写好几篇中文文章。国情如此，实在无可厚非。但近来有同行抱怨，国内的期刊大多喜欢定量研究型的文章，对于以定性研究为主（如 ethnography research, action research）的文章不是那么欢迎。我没有太多用中文发表学术论文的经验，国内学术论文发表的内情是否如此，我就不得而知了。 写学术文章、参加学术会议，其实是一种学术圈内同行的对话。用中文写，懂中文的同行能读到你的研究，很好。用英文写，懂英文的同行能读到，也不错。如果想将你的研究和全世界的同行分享的话，可能英文比较能够达到这个目的。过去几年，我发了一些英文论文，也应一些英文学术期刊 (应用语言学方面的有TESOL Quarterly, Journal of Second Language Writing, Journal of Language Learning and Technology, World Englishes)的邀请做了审稿的工作。结合我的经验，我想谈谈在英文的应用语言学期刊上发文章应该注意的几点。这种经验之谈，供有兴趣的同行参考，以共同促进我们国际学术交流的水平。 首先，论文综述的目的不仅是发现本领域目前讨论/研究过什么，什么还没有讨论过，更重要的是提出你对已有的研究的批判，以发现值得进一步研究的问题。我发现后面的一步最不容易做到了，我做学生时不容易做到，我现在指导的博士生不容易做到，我审阅的许多投稿也没有将这一步做好。 第二，在论文综述的基础上提出研究问题和研究方案。问题和方案的提出，必须是基于对以往研究 (包括内容与方法) 的批判基础上提出。 我经常发现许多论文的论文综述和后面研究问题和研究方案的提出脱节。 第三，材料的收集和分析过程一定要详细描述。无论是定性还是定量分析，要在论文综述的'基础上先提出你想观察/研究的几个方面，然后详细、具体地描述你的测量方法或分析方法。 第四，根据先前提出的几个想观察的方面，对材料一一分析。分析的过程中，可以比较和讨论前人发表的研究，通过对比, 通过引用别人的已有发现, 来了解或阐述你的新发现。材料分析和讨论的部分一定要紧紧扣住文章前面提出的研究问题，这样才能使本研究的贡献凸现出来，从而体现学术交流的精神。 说了这里，有人可能会说，这几点不是和中文学术论文的要求一样吗？其实这些就是学术文章的最基本要求，如此看来，国内的学术论文规范已经和国际接轨了。最后，说一点可能和国内很多文科学术期刊不一样的要求。 第五，文章可能要修改再投。英文期刊一般会有编辑先筛选一遍, 将研究内容和写作风格适合本刊物的文章寄给两到三个领域的同行匿名审阅。一般而言，文章一投就中的可能性很小。很多时候，编辑会综合文章审阅人的意见，让作者依审阅人的建议（往往是对上面几点做评论）一一修改后再投。这实在是好消息了，因为编辑和审稿人都认为该研究做得不错，论文的内容和写作风格基本符合该期刊的传统。作者应该根据他们的意见，将文章修改再投。如此般地修改一轮或两轮是家常便饭，千万不要放弃。 第六，反复修改，提高论文的逻辑性和表达的准确性。在论文的写作过程中，要反复修改几遍，要反复思考苛刻的读者可能会有的质难。在寄给期刊编辑部之前，一定要让你的一两个同行先“无情”地批判一番，确保没有重大的逻辑和语言表达上的问题。我发表的第一篇英文论文修改了不下十遍！现在在这方面也丝毫不敢松懈。
相信很多人会遇到这样一个类似的问题，那就是在英文论文写好之后，却苦于找不到国内经常使用的论文发表期刊有哪些。下面是根据多年的经验总结出来的其中比较受欢迎的期刊，希望对您有一定帮助。至于查重可以了解一下paperfree。谢谢！zAcademic Journal of Xi'an Jiaotong University（English Edition）Acta Geologica SinicaActa Mathematica ScientiaActa Oceanologica SinicaActa Pharmacologica SinicaActa Seismologica SinicaADVANCES IN ATMOSPHERIC SCIENCESApplied Mathematics A Journal of Chinese UniversitiesBiomedical and Environmental SciencesCell ResearchChemical Research in Chinese UniversitiesChina WeldingChinese Annals of Mathematics，Series BChinese Chemical LettersChinese Geographical ScienceChinese Journal of AeronauticsChinese Journal of Astronomy and AstrophysicsChinese Journal of Cancer ResearchChinese Journal of Chemical EngineeringChinese Journal of GeochemistryChinese Journal of Integrative MedicineChinese Journal of LasersChinese Journal of Mechanical EngineeringChinese Journal of Oceanology and LimnologyChinese Journal of Polar ScienceChinese Journal of Reactive PolymersChinese Journal of Sexually Tuansmitted InfectionsChinese Journal of Traumatology （English Edition）Chinese Medical JournalChinese Medical Sciences JournalChinese Quarterly Journal of MathematicsChinese Rice Research NewsletterChinese Science BulletinCommunications In Theoretical PhysicsEarthquake Engineering and Engineering VibrationElectricityForestry Studies in ChinaGeo-spatial Information ScienceHigh Technology LettersHunan Agricultural Science & Technology NewsletterInternational Journal of Plant Engineering and ManagementJournal of Beijing Institute of TechnologyJournal of Central South University of Technology（English Edition）Journal of China University of GeosciencesJournal of China University of Mining and TechnologyJournal of Chongqing University（English Edition）Journal of Coal Science & Engineering（China）Journal of Computer Science and TechnologyJournal of Electronics（China）Journal of Environmental SciencesJournal of Forestry ResearchJournal of Geographical SciencesJournal of Harbin Institute of Technology（New Series）Journal of Huazhong University of Science and Technology（Medical Sciences）Journal of HydrodynamicsJournal of Iron and Steel Research，InternationalJournal of Materials Science & TechnologyJournal of Nanjing Medical University（English Edition）Journal of Northeast Agricultural University（English Edition）Journal of Rare EarthsJOURNAL OF SHANGHAI JIAOTONG UNIVERSITYJournal of Shanghai Second Medical UniversityJournal of Shanghai University（English Edition）Journal of Southeast University（English Edition）Journal of Southwest Jiaotong University（Englis Edition）Journal of Systems Engineering and ElectronicsJournal of Systems Science and ComplexityJournal of Traditional Chinese MedicineJournal of Tropical MeteorologyJournal of University of Science and Technology BeijingJournal of Wuhan University of Technology （Materials Science Edition）Journal of Zhejiang University（Science）Nuclear Science and TechniquesNumerical Mathematics A Journal of Chinese Universities English SeriesPedospherePlasma Science and TechnologyProgress in Natural ScienceRare MetalsReproduction & ContraceptionScience In China （Chemistry）SCIENCE IN CHINA （Earth Sciences）Science In China （Information Sciences）Science In China （Life Sciences）Science In China （Mathematics Physics Astronomy）Science In China （Technological Sciences）Semiconductor Photonics and TechnologyThe Chinese-German Journal of Clinical OncologyThe Journal of China Universities of Posts and TelecommunicationsTransactions of Nanjing University of Aeronautics and AstronauticsTransactions of Nonferrous Metals Society of ChinaTransactions of Tianjin UniversityTsinghua Science and TechnologyWuhan University Journal of Natural Sciences
