Electrical Conductors And Insulators Flashcards
Everything
1
Q
What is a conductor
A
Material that can conduct an electric current
They are substances that offer low resistance of flow of charge
2
Q
What are the made of and why
A
Metals because the valence electrons are delocalised and can therefore move around
3
Q
What are insulators?
A
Material that cannot conduct electric current
Materials that cannot have a flow of charge
4
Q
What are they made of and examples?
A
Non metals
Plastic,wood,rubber,procelain
5
Q
Which non metal conducts electricity
A
Carbon
6
