Conductors:
In electrical engineering, a conductor is an object or type of material that allows the flow of electrical current in one or more directions. The electrons of different types of atoms have different degrees of freedom to move around. With some types of materials, such as metals, the outermost electrons in
the atoms are so loosely bound that they chaotically move in the space
between the atoms of that material by nothing more than the influence of
room-temperature heat energy. Virtually unbound electrons are free to leave their respective atoms and
float around in the space between adjacent atoms, they are often called free electrons.
The mobility of electrons within a material is known as electric Conductivity
Conductivity is determined by the types of atoms in a material and how the atoms are linked together with one another. The materials with high electron mobility (many free electrons) are called conductivity while materials with low electron mobility (few or no free electrons) are called conductivity.
The fallowing conductor materials are
- Silver
- Copper
- Gold
- Aluminum
- Iron
- Steel
- Brass
- Bronze
- Mercury
- Graphite
- Dirty Water
- Concrete
