Conductivity typically refers to the ability of a material to conduct electric current. This property is a measure of how easily electrons can flow through a substance. Materials with high conductivity, such as metals like copper and silver, allow electric charge to pass through them with very little resistance. Conversely, materials with low conductivity, known as insulators, resist the flow of electric charge. Examples of insulators include rubber and glass.

The conductivity of a material is an intrinsic property that depends on its atomic structure and the availability of free charge carriers. In solids, these charge carriers are typically electrons. In electrolytes, ions are responsible for carrying the charge. Temperature also plays a significant role; for most conductors, conductivity decreases as temperature increases due to increased scattering of electrons by lattice vibrations. For semiconductors, however, conductivity often increases with temperature as more charge carriers are excited into a conductive state.

Electrical conductivity is quantified by the SI unit of siemens per meter (S/m). It is the reciprocal of resistivity, which measures how strongly a material opposes the flow of electric current. Understanding conductivity is fundamental in electrical engineering, materials science, and many other fields, as it dictates the suitability of materials for various applications, from wiring in electronic devices to components in solar cells and batteries.
