How does copper produce electricity?

it doesnt.  it conducts electricity.

The basic rule of thumb is any metal.  Silver, gold, iron, copper, and aluminum are a few examples.  Copper is commonly used in electrical wiring because it is durable, inexpensive, and easy to bend.  \n\nAs previous stated, the "gold connectors" on your cables provide very little help.  In pure definition, they conduct electricity more efficiently than copper.  However, the cost delivers little results unless you are investing $50,000 in your home theater sytem.  Then you might tell a difference.\n\nHope it helps!

copper and aluminum are best electricity conductors. I would say lead, since it's one of the densiest material out there. Heat is caused by vibrating atoms, denser material means the atoms are closer, and it's melting point is low too. As soon as you touch it with a hot soldering iron, the heat transfers right away and melts it.

Copper ore is extracted from the Earth usually in rocks dug from strip mines. Kennecot copper in Utah has this humongous open pit near the Great Salt Lake that looks like a mountain dug into the Land. The ore rock is crushed and then run through a blast furnace (Smelter) at extremely high heat (Thousands of degrees fereinheit) which melts out the different metals in the rock including the copper. Then each metal is extracted from that mix and we have pure copper.

so that it gets ionised during electrolysis and the ions help in the conduction of electricity....

Yes.  It consists in sticking two metallic objects of different kind, usually a galvanized nail and a copper coin, in a potato or lemon. These two objects work as electrodes, producing an electrochemical reaction that generates a small amount of electricity.

A generator produces a current by moving a wire through a magnetic field.  If you had an infinitely large magnetic field, you could move in one direction forever and produce a dc current.  However, it isn't practical to do that.\n\nInstead, you put a ball of wire inside a much smaller magnetic field and you spin it.  The ends of the wire have to be touching something to complete the circuit so electrons can flow.  At one part of the circle, the wire is moving left to right across the magnetic field and causes electrons to flow in one direction in the wire, in another part of the circle, the wire is moving from right to left and the electrons flow in the opposite direction.  This is what causes the current to alternate.\n\nSo, when converting motive energy into electricity, ac current is the easiest to produce.  This is like what is produced by a car's alternator or a hydro-electric plant.

Induction. \n\nWhen you wind a conductive wire into a coil and pass a current through it, you create a magentic field that extends from the coil.  Similarly, if you hold/move a coiled wire in a magnetic field, you "induce" a current flow in the coil.  With AC, there's no need for the coils to move relative to one another. (That's how a transformer works)  The toothbrush base has a coil in it, and the AC coming out of the wall goes through a coil in the base, induces current in the coil in the toothbrush, and that current charges a cell in the handle.\n\n Here are some neat links:\n\nhttp://www.energyquest.ca.gov/how_it_works/transformer.html\n\nhttp://micro.magnet.fsu.edu/electromag/java/faraday2/

Not sure what you mean, are you talking about using 2 different metals and generating electricity from a potato?

Copper. It is so brilliant

Depending upon your application, copper probably does not make a good coil core.  If you wrap many turns of wire around a steel nail and pass a current through the wire (say from a battery) the nail will concentrate the magnetic field and you will have an electromagnet in which the tiny magnets within the steel are all aligned.  This will not happen with copper because you can not pick up copper with a magnet.  The coil will still produce a magnetic field but the copper core will not concentrate it.

Almost all power plants use some heat source (coal, natural gas, nuclear pile, geothermal heat, concentrated sun rays) to generate steam. The steam turns turbines. The turbines turn generators.\nGenerators generate electricity which is where electromagnetism comes in. A simple model is this: when you move a magnet around a wire you see a current induced in the wire. Now a generator moves a whole bunch of coils of wire around magnets (or moves magnets inside lots of coils of wire) and thus uses electromagnetism to generate electricity.

The electrons of the atoms in general is responsiblle for their bonding. Metal atoms are said to be "surrounded in a sea of electrons". Their electrons are loosely held together and they will be attracted to an area with a high positive charge. Electricity is the flow of electrons and when the electrons of metallic atoms get attracted they will flow thus creating electricity.

CuCO3 + H2SO4 --> CuSO4 + CO2 + H2O\n\nCu(OH)2 + H2SO4 --> CuSO4 + 2H2O\n\nFor the electrolysis:\n\nCuSO4 = Cu+2 (aq) + (SO4)-2 (aq)\n\nCu+2 (aq) + 2 e-1 --> Cu (metal)

The best example I can give of this is the PC that you used to type this question.  \n\nElectricity powers the whole thing i.e. 110 volts coming out of the wall right.  Well this 110 volts is useless to your PC.  For one thing it is alternating current (AC) and it is much to powerful, it would fry the inside of you PC.  So the first place the power goes is in to the PC’s power supply.  Here the 110 volt AC is converted into direct current (DC) and lowered to different voltages.  However when you scrub off this extra power heat is created due to resistance and that is why the power supply has a fan.  \n\nAlmost all light creates heat.  Light can only be created without heat from a chemical reaction. Reactions that produce light without heat are called chemiluminescent reactions. Perhaps the most familiar chemiluminescent reactions are those that occur in living organisms. Fireflies produce light without heat by a chemiluminescent reaction. Chemiluminescent reactions that occur in living organisms are called bioluminescent reactions. \n\nSound also creates heat because it takes power (usually given in watts) to switch the polarity (North and South poles) of the electromagnet and to run the voice coil of a speaker which have electrical resistance given in ohms.

Lightning basically is a discharge of static electricity. Atmosphere and ground work like two plates of a condensator.\n\nCharging a battery requires a steady current within a limited voltage range - if the voltage range is exceeded, all kinds of unwanted reactions take place which are likely to destroy the battery.\n\nI think what you are after is not use of the lightnings, but something like a cable hanging from the sky through which the electrostatic charge can be neutralized.\n\nThere are a couple of practical difficulties creating and fixating such a cable (or a sufficiently high tower). If we had them, we could indeed leach away potential differences between various layers of the atmosphere and the ground. Several science fiction writers have exploited that idea assuming availability of high temperature superconductors and spacelift cables. It might just work.\n\nSuperconductors are almost a necessity because a conventional cable that long would use up most of the energy as thermal energy released from its electrical resistance.\n\n\nSo: The use of lightnings as energy source is highly unlikely. The use of the energy which causes lightnings is theoretically possible, practically we lack the technology to make it useful. It is unlikely that we would rely on that energy if we could make space-lift cables because in that case we'd simply use solar energy collectors in space and lead down all the energy we need from the vast amount of unused solar radiation.
