A material that hinders the passage of electric charge is called an insulator.

Here's why:

* Insulators have tightly bound electrons that are difficult to move. This means that when an electric field is applied, the electrons don't easily flow, preventing the passage of electric charge.

* Conductors, on the other hand, have loosely bound electrons that can move freely. This allows for the easy flow of electric charge.

Some common examples of insulators include:

* Rubber

* Glass

* Plastic

* Wood

* Air
