electrical conductivity
Charge flow ability
Electrical conductivity is a material's ability to carry electric current.
Metals like copper and silver have high conductivity; rubber and glass have almost none.
The property matters in engineering, where choosing materials depends on whether you want current to flow or be blocked.
Conductivity varies with temperature and is measured in siemens per meter.
