FAQs on Electric Conductors and Insulators Video Lecture - Science for Grade 5

1. What are electric conductors and insulators?

Ans. Electric conductors are materials that allow the flow of electric current through them easily, while electric insulators are materials that do not allow the flow of electric current easily.

2. Give some examples of electric conductors.

Ans. Some examples of electric conductors are metals like copper, aluminum, iron, and silver. Water and the human body can also act as conductors under certain conditions.

3. What are some examples of electric insulators?

Ans. Some examples of electric insulators are rubber, plastic, wood, glass, and ceramic. These materials do not allow the flow of electric current and are commonly used to insulate wires and electrical devices.

4. How do electric conductors and insulators differ in terms of their atomic structure?

Ans. Electric conductors have loosely bound electrons in their atomic structure, which are free to move and carry electric charges. In contrast, electric insulators have tightly bound electrons that are not free to move, preventing the flow of electric current.

5. Why are electric conductors used for electrical wiring?

Ans. Electric conductors like copper and aluminum are used for electrical wiring because they have low resistance and can efficiently carry electric current from one point to another. Their high conductivity ensures minimal energy loss during transmission.
