Conductivity Meaning: Definition, Examples, and Translations
⚡
conductivity
[kənˌdʌk.tɪˈvɪt.i ]
Definitions
electrical property
Conductivity is the measure of a material's ability to conduct electric current. It is a key parameter in determining how well a substance can transmit electrical signals. Higher conductivity indicates that the material allows electric charge to flow more freely.
Synonyms
Examples of usage
- Copper has high electrical conductivity.
- The conductivity of the solution increased with temperature.
- This material has a low thermal conductivity.
thermal property
In terms of thermal properties, conductivity refers to the ability of a material to conduct heat. Materials with high thermal conductivity are efficient at transferring heat energy.
Synonyms
heat conductance, thermal transmittance.
Examples of usage

Origin of 'conductivity'
Main points about word origin
- The word comes from Latin roots: 'con-' meaning together and 'ducere' meaning to lead.
- The term was first used in English in the 19th century as scientists began to study heat and electricity more closely.
The term 'conductivity' was introduced in the early 19th century, deriving from the Latin root 'conducere,' meaning 'to lead together' or 'to bring together.' This concept was initially applied to the realms of electricity and heat, where understanding how materials can transmit energy is crucial. Over time, conductivity has become a fundamental concept in physics and engineering, influencing various applications from electrical engineering to materials science. The distinction between electrical and thermal conductivity emerged as scientists advanced their studies, leading to more precise measurements and theories. The systematic study of conductivity paved the way for the development of numerous technologies that rely on effective transmission of electricity and heat, forming the backbone of modern electrical systems and thermal management.
