distinguish between conductors and insulators.give three examples of each.

Differences between a conductor and insulator

1. A conductor allows flow of electric current through it when a potential difference is applied across its ends while an insulator does not conduct electricity unless vert very high potential difference is applied across its ends.

2. A good conductor of electricity is generally a good conductor of heat, insulators do not conduct heat too.

3. Conductors have free electrons on its surface, insulators have bounded electrons on its surface.

Example of conductor: Silver (Ag), Copper (Cu), Aluminum (Al)

Examples of insulators: Ebonite, Sulphur, Poly-vinyl Chloride.

 conducters are objects which allow electricity to flow through them. . . . . . Ex  graphite copper aluminium brass

 

Insulators are those materials which to not allow electricity to pass through them . . . . Ex wood cotton glass

 1) Those substances through which electricity can flow are called conductors while those substances through which electricity cannot flow are called isulators.

2) Electricity resistance of conductors are very low while electricity of insulators are infinitely very high.

3) Eg - metals such as silver , copper and iron while non-metals such as water , air  and wood.

conductors:-the substances which allows heat and electricity is called conductors .eg :- all metals such as silver, gold,bronze,copper,zinc

insultators:-the substances which are poor conductors of heat and electricity is called insultators. Eg:- wood, wool, cotton, silk , air

Conductors are the substances which conduct heat and electricity.Eg:water

 

 

 

Insulators are the substance which do not............conduct heat and electricity.Eg:wood,rubber slipper
