Final answer:Steeltroughs are used to carry electrical wires and cables due to their strength and good conducting properties. While insulating materials like wood can conduct electricity under high voltage conditions like lightning, metals are preferred for regular use. The phenomenon of electromagnetic induction allows an electric current to be induced in conducting materials, forming the basis of many devices.Explanation:True, steel troughs are indeed designed to carryelectricalwires and cables. They are often used in electrical installations to offer protection to the cables, and to provide an organized pathway for wire runs. These steel troughs, also known as conduits or raceways, are made from materials like steel because of their strength, and their ability to serve as a good grounding conductor. An example can be seen in power transmission and distribution where steel towers with insulating connectors are used to hold high-voltage wires aloft, which are often wrapped in insulating material for added protection. Although materials like wood are considered insulators and are not typically used in electrical installations, under high-voltage conditions like a lightning strike, electricity can travel through even such insulators. However, for controlled and low-risk transmission, metals are preferred because of their enhanced conductivity. Also, conducting materials like copper can have electric currents induced in them when subjected to a changing magnetic field, such as when a bar magnet is dropped through a copper tube. This is a manifestation of electromagnetic induction and forms the basis of many electrical appliances today.Learn more about Electrical Wire Conduits here:brainly.com/question/34790367#SPJ11...
