Q

Which of the following materials is a good electrical insulator?

🔍 Key Concepts

• Difference between conductors and insulators in basic electricity • Which common metals are known as excellent conductors • How materials like wood behave in typical dry conditions around electricity

💭 Think About

• Identify which options are well-known metals used for wiring or contacts in electrical systems • Think about which material electricians avoid as a path for current, and instead use as a support or handle around live wires • Consider whether the material allows electric charges to move freely, or tends to resist their movement

✅ Before You Answer

• Eliminate any material you know is used as an electrical conductor for wiring or contacts • Ask yourself: in safety equipment (like tool handles), which type of material is added to prevent electric shock? • Remember that some materials change behavior when wet, but think about their typical dry insulating property for this question
