how do i make a copper wire conduct more electricity?

Question

i am doing a project and need to know how to make my wires better to win

Answer 1

Use a larger wire.

Answer 2

Cryogenics is a fine answer, but when you say "project" and "win", cryogenics doesn't stand out as the economical answer.

To conduct more electricity, you need to decrease the resistance. Check out this link on resistivity, which will give you some options. Obviously, you would like to select a material with the smallest resistivity possible. As you'll see, only Silver has a lower resistivity, and that too isn't very economical.

Your best options are to tweak the geometry of your wires. You will want to keep the length of the wires to a minimum between components, and make the cross-sectional area as large as possible.

Good luck.

Answer 3

In terms of getting the most current through a given diameter and length of copper, the answers regarding temperature are accurate.

Without using any outside influence to cool the copper, all I can think of is to use bare, rather than insulated wire, and keep conductors as far apart as practical.

Answer 4

larger diameter
double and use two
provide cooling- cooler wires have higher capacity than the same wire at a higher temp.

Answer 5

You could cool them cryogenically.

You could anneal them first (get them red hot and then SLOWLY cool off in vermiculite) and then re-insulate them. Then cool it cryogenically.

Or you could just cheat and buy a superconducting tape (YBaCuO type), cool it with liquid nitrogen, and hope the judges don't notice :)
