Why are electrical engineers be interested in conductors and insulators? Why would electrical engineers or electricians be interested in conductors and insulators? Because different types of materials are used for manufacturing electrical products and equipment. … Electrical conductivity is the reciprocal of resistivity. And it means to measure the ability to conduct an electric current.
Why is it important to have conductors and insulators be a part of an electrical system? Conductors and insulators are both important in the field of electronics. Electrical conductors allow electric current to flow easily because of the make up of their atoms. In a conductor, the outer electrons of the atom are loosely bound and can freely move through the material when an electric charge is applied.
What is a conductor in electrical engineering? An electrical conductor is a substance in which electrical charge carriers, usually electrons, move easily from atom to atom with the application of voltage. … In electrical and electronic systems, all conductors comprise solid metals molded into wires or etched onto circuit boards.
What are the advantages of using electric conductors? Compared with other non-precious metals, copper wires can handle a wider load of electrical power, allowing it to use less insulation and armoring. They have high resistance to heat, eliminating most issues of overloading. Copper wires are also resistant to corrosion.

Why are some molecular compounds good conductors of electricity?
Covalent molecular substances which are acidic or basic react with water producing free mobile atoms. The resulting ions are able to move freely throughout the solution carrying charge and hence conducting an electric current. Strong molecular substances only form between the atoms within the molecules.
