ELECTRICAL CONDUCTIVITY Meaning and
Definition
-
Electrical conductivity is a fundamental property of a material that describes its ability to conduct electric current. It is a measure of how easily electric charge flows through the material when a potential difference is applied across it.
In simple terms, electrical conductivity refers to the ability of a substance or material to allow the movement of electric charges, such as electrons or ions, through it. It is commonly denoted by the symbol σ (sigma) and is measured in units of siemens per meter (S/m) or mho per meter (℧/m).
Conductivity depends on various factors including the type of substance, its physical structure, temperature, and impurities present. Materials that have a high number of free electrons, such as metals, generally exhibit excellent electrical conductivity. In metals, the outermost electrons of atoms are loosely bound and can easily move between atoms when an electric field is applied.
On the other hand, insulators have very low electrical conductivity since their electrons are tightly bound to their parent atoms, impeding their movement. Semiconductors, like silicon, fall in between conductors and insulators, showing moderate electrical conductivity that can be controlled by changing conditions such as temperature or impurity levels.
Electrical conductivity plays a crucial role in various aspects of modern technology, including electronic devices, power transmission, and telecommunications. It is also an important property in fields such as materials science, physics, and chemistry, where the flow of electric current is involved.

Etymology of ELECTRICAL CONDUCTIVITY
The word "electrical" is derived from the Latin word "electrum", which originally referred to a type of amber that displayed an attractive force when rubbed. The term "electricity" was coined in the late 16th century to describe this mysterious force.
The word "conductivity" is derived from the Latin word "conductus", which means to lead or convey. The term "conductivity" was first used in the mid-19th century to describe the ability of a material to conduct or transmit electricity.
Therefore, the etymology of "electrical conductivity" comes from combining the Latin roots of "electrum" and "conductus" to describe the property of a material to transmit or conduct electricity.
