Level 3️⃣ Video #1: Conductors and Insulators | How to test?

What is the primary difference between an electrical conductor and an electrical insulator?

• Conductors are always metals, while insulators are always plastics.

• Conductors allow electricity to flow easily, while insulators restrict its flow.

• Conductors are typically solid, and insulators are typically liquid.

• Conductors generate electricity, while insulators store it.

How do electrons behave in a good electrical conductor?

• Electrons are tightly bound to their atoms and cannot move.

• Electrons jump freely from atom to atom, carrying electrical charge.

• Electrons remain stationary within the material, creating static charge.

• Electrons only move when the material is heated to a high temperature.

Why do electrical insulators prevent the flow of electricity?

• Their atoms are too small to hold electrons.

• They have too many protons, which block electron movement.

• Their electrons are tightly bound to their atoms and cannot move freely.

• They absorb all electrical charge, preventing it from passing through.

Which of the following items is an electrical conductor?

• Bluetack

• Rubber band

• Coin

• Glass vase
