5 types of conductors
copper, gold, steel, silver, iron
where does insulator use
Insulators are widely used in building electrical equipment and systems and play an important role in electrical safety.
What is static electricity caused by?
The separation of positive and negative charges within a material.
What occupies 66% and 34% of the planet (in space book)
earth's surface is 66% water and 34% land
Why do we need a conductor?
because electrical conductor is a material that allows electric charges to flow through them easily, with less opposition or resistance to the flow of charges.
Why you need an insulator?
They prevent electric shocks by covering materials that carry electricity.
What kind of charge does an electron have?
Negative charge
Anything in the universe (except planets)
Dark Energy, Dark Matter, General Matter
What are the electrical properties of a conductor?
High conductivity and low resistance, many free electrons in conduction band, no energy gap between valence band and conduction band
What are the electrical properties of insulators?
Breakdown Voltage All insulators will conduct heat and electricity if subjected to extremely high voltages.
Why do we coat wires with plastic or rubber?
because they are insulators and do not allow electric current to pass when we touch those wires.
The number of stars in the universe
About 10 billion stars
