A material that has a very high resistance would be classified as what?

A material that has a very high resistance is classified as an insulator. Insulators are substances that do not conduct electricity well due to their high resistance to the flow of electric current. This high resistance is a key characteristic of insulators, allowing them to effectively prevent the flow of electric charge and to protect users from electric shock.

In practical applications, insulators are crucial for safeguarding electrical currents within conductor systems, thereby ensuring that electricity only flows where it is intended to. Common examples of insulators include rubber, glass, and certain plastics. These materials provide a barrier against electrical conduction, making them essential in electrical installations and safety measures.

The other classifications do not fit the description of a material with high resistance. Conductors, for instance, have low resistance and easily allow the flow of electric current, while superconductors exhibit almost zero resistance under specific conditions. Resistors are components that resist the flow of current but are designed for specific applications where controlled resistance is needed.
