What does the term "electrical insulation" refer to?

The term "electrical insulation" specifically refers to materials designed to prevent the unwanted flow of electricity. Insulation is essential in electrical applications as it serves to protect people from electric shock, prevents short circuits, and ensures the safe operation of electrical systems. These materials resist the flow of electric current, ensuring that electricity is contained within the intended pathways, such as wires or circuits.

For instance, rubber and plastic are common insulating materials that cover wires, keeping the conductive parts safe from accidental contact. This property is critical for maintaining safety standards in electrical installations and protecting equipment and personnel from hazards associated with electrical faults.
