That question is very hard to answer, in fact it is impossible to give you a short answer because there are whole books written about "How to generate electricity". To give you just a quick idea, you would need to make a whole lot more than just one big coil of wire. You would need a workshop and lots of tools to be able to make an electrical machine such as a generator to produce DC (Direct Current) or an alternator to make Altenating Current (AC).
Those machines must have lots of big metal parts with heavy copper wire windings and lots more pieces.
Apart from that, you would also need some sort of engine to turn the generator or alternator fast enough to make the power you want to produce. Why not go to your local library or a bookshop to read some books about Electrical Engineering? Look up "alternators" and "Transformers" in the book index to find the right books to read. There is an answer on how to make an electro-magnet. You can read it if you click on the link to the Related Question shown below.
A light bulb connected between to wires, each having 300 volts to ground that are in phase, will not light, because there is no differential voltage available to do any work. If each wire has 300 volts to ground and are out of phase (600 volts between them) the light bulb will be lit, if it is rated at least for 600 volts, otherwise it will burn out.

Copper wires and satellite transmission.
Quartz.
Couple of things wrong here. 30 isn't a wire size. If you mean a wire that can carry 30 amps that would be # 10. Now it depends on how many # 10 wires you want to put into a conduit that governs the size of the conduit.

Copper. The main grade of copper used for electrical applications is electrolytic-tough pitch (ETP) copper (CW004A or ASTM designation C11040). This copper is at least 99.90% pure.
Two wires are needed for 220 volts.
I think copper is cheaper.
Usually, you use ETP (electrical grade) copper, which is at least 99.9% pure. It could be different for special applications.
we use copper in wires because it is a conductor of both heat and electricity
Electrical wires are made from copper, as copper is a good conductor of electricity.
If you mean 2 bare copper wires those are the ground wires. Tie them together and then connect the light fixture ground wire which will be green or bare copper to those ground wires.
no its light. its in wires and those are light. i scrap wires for the copper to sell. i would know
Copper has been used lately in wires and cables like coaxial and electric wires.

Copper. Copper is an excellent conductor.
