What else can I help you with?
Do a slab of n type material carry a net negative charge?
No. The "n" and "p" does not refer to the negative or positive charge, but to the fact that there are atoms that can easily "donate" electrons (n-type), or atoms that can easily "accept" electrons (p-type).
What is a material which electrons do not travel through easily called?
A material through which electrons do not easily travel is called an insulator. Insulators have high resistance to the flow of electric current due to the lack of free electrons available to carry the charge. Examples of insulators include rubber, glass, and plastic.
Why do metals conduct electricity?
Metals conduct electricity because they have free-moving electrons that can carry electric current through the material.
How does the electrical conductivity of a material change with temperature?
The electrical conductivity of a material generally increases with temperature. This is because at higher temperatures, the atoms in the material vibrate more vigorously, allowing more free electrons to move and carry electric current.
How can you tell if a material is a good conductor or not?
A material is a good conductor if it allows electric current to flow through it easily due to the presence of free electrons. Metals like copper and silver are good conductors because they have many free electrons that can move easily. Insulators, on the other hand, are poor conductors because they do not have free electrons to carry current.
Why do materials carry current?
Materials carry current because of the way the electrons of the material behave. Current is proportional to the number of electrons. If the electrons are loosely bound on the material then they are available to carry current along the material. Copper is a common metal who's configuration means that the electrons are loosely bound and as such is very good at carrying current. If on the other hand the electrons are tightly packed into the atoms in the material then they aren't available to carry current. Materials such as glass and plastic are good examples.

Is metal a conductor of electricity?
For a material to conduct electricity, it must have free movable electric charges, such as free electrons or free ions, in order to 'carry' electricity. In the case of metals, there is a 'sea' of delocalized electrons. These free electrons can 'carry' the electricity, and thus, it is a conductor.

Are there protons in electric ciruits?
Wherever there is material, there are protons. But protons are not the things that carry the charge around in electrical circuits. Electrons do that.
Why are metals conductive?
Metals are conductive because they have free-moving electrons that can carry electric current easily through the material.

Metals conduct electricity because they have free-moving electrons that can carry electric current through the material.
A material that doesnt allow electrons to move through it easily is an?
insulator. Insulators have high resistance to the flow of electric current, which hinders the movement of electrons through the material. This property makes insulators useful for applications where electrical conductivity needs to be limited.
What is A material that allows electrons to move freely is?
A material that allows electrons to move freely is called a conductor. Conductors, such as metals like copper and aluminum, have a high density of free electrons that can move easily in response to an electric field, allowing them to carry electric current efficiently. In contrast, materials that do not allow free movement of electrons are known as insulators.
Why do wires use metals?
The purpose of a wire is to carry some sort of electrical signal. This requires that the electrons in the material be able to move freely. Materials with free movable electrons are called "metals".
What does conductor mean in science?
It means that it's a material whose outer shell electrons move freely across the surface of the material. Conductors can carry an electric current
