FAQs on Conductors & Insulators Video Lecture - Physics Class 12 - NEET

1. What is the difference between a conductor and an insulator?
Ans. A conductor is a material that allows the flow of electric current, while an insulator is a material that does not allow the flow of electric current. Conductors have a high number of free electrons that can move easily, whereas insulators have tightly bound electrons that do not move easily.
2. What are some examples of conductors and insulators?
Ans. Some common examples of conductors include metals like copper, aluminum, silver, and gold. On the other hand, materials like rubber, plastic, glass, and wood are examples of insulators.
3. How does the conductivity of a material affect its use as a conductor or insulator?
Ans. The conductivity of a material determines its ability to conduct electric current. Materials with high conductivity, such as metals, are used as conductors in various electrical and electronic devices. Insulators, on the other hand, have low conductivity and are used to prevent the flow of electric current.
4. Can a material be both a conductor and an insulator?
Ans. No, a material cannot be both a conductor and an insulator. Conductors and insulators are distinct types of materials based on their ability to conduct electric current. However, some materials, known as semiconductors, have properties that lie between those of conductors and insulators.
5. How does temperature affect the conductivity of materials?
Ans. In general, the conductivity of conductors decreases with increasing temperature, as higher temperatures cause more collisions between electrons and atoms, impeding the flow of current. On the other hand, the conductivity of some insulators may increase with temperature due to the release of trapped charge carriers.
