Question

What is a conductivity? state its si unit​

Answer 1

Answer:

=> Conductivity. Conductivity is the measure of the ease at which an electric charge or heat can pass through a material. A conductor is a material which gives very little resistance to the flow of an electric current or thermal energy. Materials are classified as metals, semiconductors, and insulators.

Resistivity has the SI unit "ohm metre" (Ω⋅m). ... Conductivity, σ, is defined as the inverse of resistivity: Conductivity has SI units of "siemens per metre" (S/m).
