Materials that can conduct current (silver, gold, aluminum, copper, etc.) contain large numbers of loosely held electrons. Their resistance to the flow of current is measured in just a few millionths of an ohm per centimeter. Insulators — such as glass, rubber, and plastic — have very few loosely held electrons and their resistance to the flow of current is measured in a few million ohms per centimeter.
