Conductors and insulators
MADE BY NEEL MALHOTRA
What is an electrical conductor? What are the
examples of a electrical conductor?
Some materials which allow an electric current to flow
through them are calledconductors of electricity.
 Examples of some conductors are:
1.
2.
3.
4.
5.
6.
ALUMINIUM
SILVER
COPPER
GOLD
IRON
BRASS
BASICS ON ELETRICAL CONDUCTOR !!
Silver is the best conductor of electricity.
The second best conductor of electricity is copper.
We usually have wires made up of copper because
copper is easy to find and is cheap enough to buy.
REMEMBER THAT WATER IS ALSO A
CONDUCTOR OF EECTRICIRTY!!!!!!!!!!!!
Insulators
Some materials which do not allow an electric
current to flow through them are calledinsulators
of electricity.
Insulators do not allow any current to pass through
them.
These protect us from the harm that electric current
can cause.
Wires are always covered with an insulator.
Rubber, plastic, and glass make the best insulators.
Examples of insulators
GLASS
RUBBER
PLASTIC
CLAY
WOOD
COTTON
PAPER
BACIS OF INSULATOR
Glass is the best insulator of electricity.
Plastic is the second best insulator of electricity.
REMEMBER THAT INSULATORS ARE VERY
USEFUL IN YOUR DAILY LFE!!!!!
