Fiber optic cables, made from glass, are gradually being used to replace copper telephone and cable television lines. It will be some time before all the lines are fiber optic, however.
No, gold will not replace copper from a copper sulfate solution through a displacement reaction. Gold is less reactive than copper and cannot displace it in a chemical reaction.
Yes, copper is corrosive and can cause damage to other materials through a process called oxidation.
Silver would most likely replace copper in high-performance electronics, such as in conductive materials for advanced technologies like touch screens, solar panels, and RFID tags. Silver's superior conductivity and resistance to corrosion make it an ideal candidate for applications that demand efficient and durable electrical connectivity.
copper will replace silver in silver nitratesolution will precipitate silver and oxidize copper turning to copper nitrate
Copper, silver, and gold are three materials that make good conductors of electricity due to their low resistance and high conductivity properties.

Copper
Copper is used for telephone wires because it is the second best conductor of electricity after silver (which is a little pricey).
Raw materials for TVs come from various sources around the world, including metals like copper, aluminum, and gold; minerals such as quartz and rare earth elements; and plastics derived from oil and natural gas. These materials are mined, processed, and manufactured into components that are then assembled into the final product.
Mainly copper.
Mainly all telephone wires are made of copper with a plastic coating for insulation. Older form of telephone wire had a paper or pulp insulation over the copper wire. They are also a twisted pair cable.

Nickel cannot replace copper in copper II sulfate because nickel is higher in the electromotive series than copper.
coaxial cable has a solid copper or copper-clad-steel centre conductor surrounded by a non-conductive dielectric insulating material. The dielectric is surrounded by foil shield/s and/or copper braid/s which form the outer conductor and also shield against electromagnetic interference (EMI). The outer conductor/shield is encased in a PVC jacket.
