Which of the following terms describes a material that limits the flow of electricity?

The term that describes a material that limits the flow of electricity is an insulator. Insulators are substances that do not allow electrical current to pass through them easily. They are typically used to protect us from the dangerous effects of electricity by providing a barrier that prevents electrical flow. Common materials that act as insulators include rubber, glass, and plastic, which have tightly bound electrons, making it difficult for electricity to flow.

Conductors, on the other hand, facilitate the flow of electricity due to their loose electrons, making them ideal for wiring and electronic components. A source refers to the origin of electricity, such as a battery or power outlet, while ground refers to a safety mechanism that provides a path for electrical current to safely dissipate into the earth in case of a fault. Understanding these definitions clarifies why insulator is the correct choice in this context.
