Which term describes a material that resists electrical flow, also known as a nonconductor?

• A. Conductor
• B. Insulator
• C. Volt
• D. Current

Answer: (B)

The main idea here is how materials interact with electricity. A material that resists the flow of electric current is an insulator. Insulators have high resistance because their electrons are tightly bound to atoms and don’t move freely, which stops current from passing easily. This is why insulators are used to coat cords and protect housings in devices, adding safety in environments like salons and spas. The opposite term, a conductor, is a material that lets current flow readily. A volt is a unit of electrical potential, not a property of a material, and current refers to the actual flow of electric charge, not the material’s behavior.
