What cable consists of a single copper wire surrounded by layers plastec and is used to connect TV?

The cable that consists of a single copper wire surrounded by layers of plastic and is used to connect a TV is known as a coaxial cable. It is commonly used to transmit television signals, but it can also be used for other purposes, such as carrying data and broadband internet signals. Coaxial cables have a cylindrical shape, with the copper wire in the centre surrounded by several layers of insulation and a plastic jacket. This design helps to reduce interference and maintain signal quality over long distances.
