Electricity flows through copper or aluminium ... Metals with more free electrons, like copper or silver, are the best conductors - they have the least resistance. Metals with fewer free electrons ...

Silver is the best metallic conductor of heat, with a thermal conductivity of about 430 W/mK. This property makes silver an attractive option for heatsinks. However, like diamond, silver is ...

Standard metal wires get worse at conducting electricity as they ... have been working to find better conductors for nanoscale electronics, but so far the best candidates have had extremely ...
