Summary:
What is a Good Conductor of Electricity?
Pure silver is the best conductor of electricity, yet unsurprisingly, it is not one of the metals that are used to carry electricity most frequently. There are a few disadvantages to the widespread use of pure silver. The first problem is that metal corrodes over time, leading to problems with the "skin effect," or the uneven distribution of current that can happen with high-frequency currents. The second disadvantage is the most obvious: running silver wire through a building is simply too expensive; it is far more expensive than running aluminum or copper.
