Conductivity refers to the ability of a material to conduct or transmit electricity, heat, or sound. In the context of electricity, it is a measure of how easily electric charge can flow through a substance. The higher the conductivity, the more easily it allows the flow of electric current. Conductivity can vary between different materials; metals typically have high conductivity, while insulators like rubber or glass have low conductivity. In addition to electrical conductivity, the term can also apply to thermal conductivity (the ability to conduct heat) and acoustical conductivity (the ability to conduct sound).
