Electrical conductivity tells us how well a material will allow electricity to travel through it. Other poor conductors include titanium, lead and chromium. This value is expressed in Watts per meter per degree Kelvin W/m•K following the S.I. By the same token, the most effective conductors of electricity are metals that have a single valence electron that is free to move and causes a strong repelling reaction in other electrons. It can be used in a variety of applications for dust and particulate control, electrical discharge, and where thermal dissipation is required. The higher the conductivity of the material, the faster the heat transfer. The metal, found in 2017, contradicts something called the Wiedemann-Franz Law, which basically states that good conductors of electricity will also be proportionally good conductors of heat, which is why things like motors and appliances get so hot when you use them regularly.. https://www.education.com/science-fair/article/which-metal-conducts-heat-best Silver is the best conductor when compared to all other metals detected with metal detectors.
