Q.2) Answer any one of following (2M)
1. Write the difference bet conductor and insulator
2. Write the difference bet Heat and Temperature
Answers
Answer:
1. difference b/w Conductor and insulator:-
- Conductors allow the flow of electrons through them. Insulators don't.
- Conductors have a high melting point and are hence used in electrical appliance. Insulators can't
- eg of conductor- copper, gold, aluminium
- eg of insulator - plastic, rubber, wood.
Answer:
1) Difference between conducters and insulators.
Explanation:
1. Conductors anticipate free flow of electric current because electrons roam freely from one atom to another with ease. Insulators, on the other hand, oppose electric current because they won’t permit free flow of electrons from one particle to another.
2.)Conductors can easily transfer energy in the form of electricity or heat, for that matter. However, insulators cannot transfer electrical energy so easily so they resist electricity.
3.)Conductors can easily pass electricity through them because of the free electrons present in their atomic structure, but insulators, on the other hand, cannot pass electricity through them.
4.)Conductors are substances whose atoms do not have tightly bound electrons thus they are free to roam around in one or many directions. However, electrons are tightly bound within atoms in case of insulators thereby restricting any movement of electrons within the nominal range of applied voltage.
5.)Conductors usually have a low resistance, but not zero resistance unless they are super conductors. Insulators have a high resistance to electricity.
6.)Conductors conduct electricity while insulators insulate electricity. For example, the metallic wire in an electric cord is a conductor, while the sheath or the protective cover is the insulator.
7.)Touching a live conductor might kill you. On the other hand, if you touch a live insulator, it won’t even hurt a bit because it resists electric current.
