An electric current flowing through a wire mostly flows on the surface, not the interior of the wire. The reason for this is that electrons repel each other, so they want to get as far away from each other as they can. This is called "skin effect". Current flowing through a wire *does* penetrate the wire to a certain depth, called the "skin depth". The fact that current flows mostly on the surface of the wire leads to an increase in wire resistance at higher frequencies. Therefore, there's a type of wire called "Litz Wire" which consists of many small insulated strands of wire woven into a cable form. This is used to get the minimum possible resistance when driving a current through a wire.

In other words: Get the silver plated instead.

Thank you I appreciate it.
