Tungsten, copper, and silicon are all good conductors of electricity, but silver is the best conductor of electricity among them. The electrical conductivity of silver is 63 × 10^6 S/m, while the electrical conductivity of tungsten is 18 × 10^6 S/m, the electrical conductivity of copper is 59 × 10^6 S/m, and the electrical conductivity of silicon is 4 × 10^4 S/m.
