An electric circuit
can be used to test if a material is an
Electrical insulator
such as
Wood**Plastic
Rubber
Which
Does not allow electric current to flow through it
Electrical conductor
such as
Iron
Steel
*Copper
Which
Allows electrical current to flow through it
is a
Closed circuit
When
There are no gaps in it
and thus
Electric current flows through it
is a
System
made up of parts such as
Battery
Bulb
Wire
Switch
Which are used in a
Circuit diagram
is an
Open circuit
When
There are one or more gaps in it
and thus
No electric current flows through it
