FAQs on Electric Conductors and Insulators Video Lecture - Science (Curiosity) Class 7 - New NCERT

1. What are electrical conductors?

Ans.Electrical conductors are materials that allow electric current to flow through them easily. They have free electrons that can move about, facilitating the transfer of electricity. Common examples of conductors include metals like copper, aluminum, and silver.

2. What are electrical insulators?

Ans.Electrical insulators are materials that resist the flow of electric current. They do not have free electrons, which makes it difficult for electricity to pass through. Common examples include rubber, glass, and plastic. Insulators are often used to protect us from electric shock.

3. How can you test if a material is a conductor or an insulator?

Ans.You can test if a material is a conductor or an insulator by using a simple circuit. If the material allows an electric current to flow when connected to a battery and a light bulb, it is a conductor. If the light bulb does not light up, the material is likely an insulator.

4. Why are conductors important in electrical circuits?

Ans.Conductors are crucial in electrical circuits because they enable the flow of electric current, allowing devices to function. Without conductors, electricity would not be able to travel from one part of a circuit to another, making it impossible for appliances and gadgets to work.

5. Can some materials act as both conductors and insulators?

Ans.Yes, some materials can act as both conductors and insulators, depending on conditions such as temperature or the presence of impurities. For example, graphite is a form of carbon that can conduct electricity, while its pure form acts as an insulator under certain conditions.
