Question
Which of the following is the best conductor of
electricity?Solution
The metal with the highest conductivity is silver (Ag). Even though it is the best conductor of electricity, there are two reason silver is not used very frequently over other conductors: 1) it is a precious metal and thus has a high price for the amount of material used and 2) it corrodes or oxidizes easily.
