Which element has the highest electrical conductivity?
ChemistryMaterials
Quick Answer
Silver has the highest electrical conductivity of all elements. Copper is used more often in wiring because it is cheaper and still conducts extremely well.
The Full Story
Silver is the best electrical conductor among the elements, with the lowest electrical resistivity at room temperature. In practical terms, electrons move through silver more easily than through any other metal. Despite that, silver is rarely used for ordinary electrical wiring because it is expensive and tarnishes. Copper is the usual choice for cables and power lines because it offers an excellent balance of conductivity, cost, and durability.
