I was "SHOCKED" to see how many good sites there are on this topic.\nHere are a few!!!\n\nhttp://www.1728.com/project2.htm\n\nhttp://www.electricityforum.com/basic-electricity.html\n\nhttp://harada-sound.com/sound/handbook/basicelec.html\n\nhttp://www.williamson-labs.com/basic-ele.htm

It doesn't hurt to be inquisitive on Yahoo Answers and get sources of information for stuff you are doing for your engineering homework.  As long as you aren't posting questions directly from your homework and as long as you actually use this as simply a starting point for your research, keep up the good work.\n\nAs far as Electrical Engineering stuff.  I have found what I needed a few times from Google.com and Wikipedia.  However, that is a difficult course and I would recommend tutoring or study groups if you are struggeling.  \n\nGood Luck.

Here is something that may or may not help\n\nIf you take a largish non polarized capacitor\n≥45µF\nand you apply AC 120V 60Hz to one side of it\nwith no ground reference! \nyou can then place \na small wattage low voltage lamp across the \ncapacitor terminals and it will light.\n\nThis is a way to send power over a single conductor.\nI have done this.\nI think it would also work with a coil instead of a cap.\n\nAs far as I can tell\nTesla wanted to use this principle to \npower the Earth\nusing the earth as the single conductor.\n\ndo you mean generate electric power at the other site?\ndo you mean energize an electric generator?\nmaybe for a very focussed wave and relatively small distance or a tiny amount of power.\nBut that is sort of why we use wires so much!\n\ndon't RFID cards transduce a wave and send it back\nI mean technically that is an example right?

Just the usual stuff.  Use an electrolyte (H2SO4/HNO3), a couple of electrodes, a reduction table of half cell potentials, and some electricity.

1. Be very careful.  Working with electricity without understanding the risks is very dangerious.\n2. I don't know if there is anywere on the web but your local library will have many books on home wiring.\n3. After gaining an understanding of basic wiring you will need to research the local building codes for your area.

Electricity is a property of matter that results from the presence or movement of electric charge. Together with magnetism, it constitutes the fundamental interaction known as electromagnetism. Electricity is responsible for many well-known physical phenomena such as lightning, electric fields and electric currents, and is put to use in industrial applications such as electronics and electric power.

sure. go to a science store or look up schematics on the web.

Ok, i am an electronics teacher, but it will be very lengthy and cumbersome to explain, because you have to go as deep as electrons and positive and negative charges, so i can advise you to go to www.wikipedia.com and you will find a satisfactory answer.

I could suggest several considerations.  First P=IE, that is Power equals the electrical current (I in Amperes) times the voltage (E in volts).  Current is like the flow of water in a pipe and voltage is like the pressure causing the water to flow.  If you use the water to drive a hydraulic piston (say to hoist an automobile for repair) you can use either a small piston and high pressure or a larger piston and lower pressure.  Which is more cost effective?\n\nIn the United States, electric power is delivered to neighborhoods using three wires (three phases) strung along telephone (power) poles.  Only two of the wires are led to a single residence but the neighborhood must use all three wires to balance load on the wires.  Within a house electricity passes from only one wire (phase) to ground or earth to light a lightbulb which uses 110 volts.  The clothes dryer that needs far more power is connected between two of the supply wires (two phase) and to ground to supply 220 volts.  A machine shop might connect a very large motor to all three supply wires to obtain even more power at 440 volts.\n\nSix volts or even 12 volts DC in an automobile circuit can be touched with little danger.  It is less dangerous to accidentally touch a 110 volt AC wire than a 220 volt source and 440 volts is most dangerous.\n\nTherefore, the selection of voltage depends in part on safety and then on the size of the job to be tackled and also economic factors.  The higher the required current, the larger the required wires using expensive copper.  Increasing the voltage reduces the needed current and reduces the needed copper to do a given job.  The higher the required voltage, the more expensive the required electrical insulation will be.  Engineers must determine the best trade off of many factors.

Best Answer Chosen By Voters:\nLet me give you a more understanding answer to what electricity is than Ubi did.\n\nTo study electricity you must first understand something very important...    \n \nWhat do lightning, a flashlight, an alarm clock battery, and a toaster have in common?\n  \n \n Are you still thinking? Here are more items to add to the list: a computer, a car battery, a light bulb, the shock you feel when you shuffle across a carpet and then touch something. Their common link isn't something magical...\nThey are powered by a form of energy called ELECTRICITY. \nIt helps us do many things.\n  \n\n\n------------------------------------------------------------\n \nThe Atom \nTo study electricity you must first understand something very important...    \n \nEverything is made of atoms. They are a very tiny particles made up of even tinier particles. The central part of an atom, called the nucleus, contains protons and neutrons. Orbiting around the outside of the nucleus are electrons. Protons, neutrons and electrons have their own characteristics. One of these is called an electrical charge. Protons carry a "positive" charge while electrons carry a "negative" charge. Neutrons carry no charge. Electricity happens when electrons get temporarily taken away from an atom.    \n \nNow that we have more information, it's time to look at our definition of electricity. \nELECTRICITY \nis a form of energy produced by the movement of electrons.   \n  \nA Little Electrical History...  \n                            Just 200 years ago, electricity was not used to power anything in the world. \n                            Who do we have to thank for discovering how to use it? \n     \n Electricity was not invented. \nIt occurs naturally in our world. People, however, have invented ways to measure it and to control it for our use. \nBen Franklin started working with electricity in 1740's. He believed that lightning was a flow of electricity taking place in nature. He performed his famous kite experiment in 1752 which proved that electricity and lightning were the same thing.\n\nLearn more about this great man and his experiment at \nThe Franklin Institute Online.  Thomas Alva Edison is another name important in the history of electricity. In the late 1800's he developed 1,093 inventions, but his most famous is the incandescent light bulb. He wanted to bring light into homes and factories. Up until then people used candles or whale oil lamps for light. \n \n\nHow many kinds of electricity are there?\n\nLet's think about the above examples for a minute... Did you notice that they don't all have wires! Electricity doesn't exist only in things with wires. The reason is that there are two kinds of electricity: static and current. \n   \n Try to figure out what types of electricity these are\nSTATIC ELECTRICITY:The Facts/ CURRENT ELECTRICITY:The Facts \na build up of electrons\n                              the steady flow of electrons between objects or places. It comes from far away on wires.\n \nstays in one place until it jumps to an object\nneeds a conductor, a substance that allows electrons to move easily through it\n \n                                   does not need a circuit \n needs a closed circuit to flow\n \nthe kind of electricity you feel after you drag your feet across a carpet and touch someone or something\n                                  the kind of electricity that powers the appliances and heat in your home\n \nlightning is static electricity on a more spectacular scale\n the kind of electricity in a battery\n\nHope this helps, worked really hard on it.
