Timothy Thiele. When you think of the term conductor, you think of anything that conducts electricity through something, often wires. Electrical wires may be made of copper or aluminum metal, both of which conducts electricity, but copper is a much better conductor than aluminum and a safer option. When electricity flows from one point to another through something like an electrical wire, we call this conductivity.
