The three categories of material used in the electrical industry are as follows:
1. Conductors: These are materials that allow the flow of electric current through them. Copper and aluminum are commonly used conductors in electrical wiring and transmission lines.
2. Insulators: These materials are designed to prevent the flow of electric current. Insulators are used to protect people and equipment from electric shocks and to prevent short circuits. Common insulating materials include plastic, rubber, glass, and ceramics.
3. Semiconductors: These materials have electrical conductivity between that of conductors and insulators. Semiconductors are essential for the functioning of electronic devices and are used to control and manipulate electric signals. Silicon and germanium are widely used semiconductors in the electrical industry.
