Application of electrical conductor and insulator

Electrical insulators, such as glass, rubber, ceramics and plastic, exhibit a resistance that inhibits or entirely prevents electricity from traveling through. In contrast, electrical conductors such as most common metals – silver, copper and steel – exhibit little resistance to electrical flow that encourages the travel of electricity. Examples of each can be found in most mundane settings. Charging cables use both to move electricity from a power source to an electronic device.
When a material's electrons have little freedom to move from atom to atom, the material functions as an electrical insulator. Examples of this include glass, rubber, plastic and air – the former three of which are often used in electronic circuitry and wiring. Rubber, in particular, is often used as a wearable insulator to protect electricians and other specialists from shocks that could be dangerous or deadly without protection. At the same time, plastic is used in the coating of power cables to ensure that electricity flows only from the power source to your electric devices. In power generation, electric cables are protected from the metal of the towers that carry them with large glass insulators.
