Copper and zinc are both metals, which means that they have a relatively high electrical conductivity. This is because the atoms in metals are arranged in a way that allows electrons to move freely between them. When an electric current is passed through a metal, the electrons in the metal are pushed in one direction, creating a flow of electricity.

The electrical conductivity of a metal depends on several factors, including the temperature, the purity of the metal, and the presence of any defects in the metal. The higher the temperature, the more the atoms in the metal vibrate, which makes it more difficult for electrons to move freely. The purer the metal, the fewer defects there are in the metal, which also makes it easier for electrons to move freely.

Copper is a very good conductor of electricity, and it is often used in electrical wiring and other applications where high electrical conductivity is required. Zinc is also a good conductor of electricity, but it is not as good as copper. However, zinc is often used in combination with other metals, such as copper, to improve the electrical conductivity of the alloy.
