Caption: Electrical conductivity of diamond. Footage of an experiment demonstrating the lack of electrical conductivity for diamond. A piece of unpolished diamond (a form of carbon) is connected to electrodes at lower centre, forming part of an electric circuit. The light bulb (right) is unlit, as there is no power in the circuit. When the power is switched on (upper left), the bulb remains unlit. This demonstrates that diamond does not conduct electricity. It is an electrical insulator because its valence electrons are tightly bound in covalent bonds. For footage of the same experiment, with a different form of carbon called graphite, see clip K004/5708.
