🔍 Key Concepts

• Dielectric in basic electrical theory • Difference between conductor, insulator, and semiconductor • How electric fields interact with different materials

💭 Think About

• Ask yourself: In which type of material do electrons move freely, and in which type are they tightly bound? Which one best matches a dielectric? • Think about where you might find dielectric materials in real equipment, like capacitors — what role do they play between two conductive plates? • Compare each option: which ones describe allowing current to pass, and which describe preventing current from passing?

✅ Before You Answer

• Be clear on the basic definitions of conductor, insulator, and semiconductor before choosing. • Verify whether a dielectric’s main job is to permit current flow or to support an electric field without conducting. • Check that the option you select matches how materials are used between capacitor plates in electrical systems.
