i think wire, but I'm not completeley sure.
Silver, if cost is no problem. For reasonably priced wires that are readily available, copper. Aluminum is by far the poorer conductor in use today.
we will introduce you to the enameled wires of different conductors.
Because copper makes the best conductors - Snakester1962 (Supervisor)
Mainly metals. Silver is the best but copper is nearly as good and a lot cheaper. Aluminium is about 40% worse but is popular for overhead cables because they are lighter.

You do not need three 12 volt batteries to get 24 volts, all you need is two batteries. So I assume by using three batteries you want to increase the amperage. Wire two of the batteries in series and then wire the third battery to the second battery in parallel and you will have 24 bolts. Or you can just wire two 12 V batteries in series to get 24 V.
Wire. conductors. Wire made into a coil, an inductor.
No they do not. They have batteries in them, but the batteries are not replaceable. Information from ChaCha.com
That depends on what voltage your batteries are,
Positive wire is red, at least on automobile batteries.
The best conductors of electricity have that they are all metals in common.
Cutting through the wire terminal of a battery may be hazardous to your health depending on the battery. Car batteries can be very dangerous and this is not recommended. For other batteries a good pair of insulated side cutter will do the job.
