Which four metals have the least resistance?

Which four metals have the least resistance?

• A. Iron, Nickel, Titanium, Zinc
• B. Platinum, Palladium, Copper, Silver
• C. Silver, Copper, Gold, and Aluminum
• D. Lead, Tin, Bronze, Brass

Answer: (C)

The idea here is that resistance in metals follows how easily electrons can move through the material. Materials with lower resistivity offer less opposition to current, so they have the least resistance for a given size and shape. At room temperature, the lowest resistivity among common metals is found in silver, then copper, then gold, and then aluminum. That makes these four the ones with the least resistance. So the four metals that have the least resistance are silver, copper, gold, and aluminum. The other choices include metals that are less conductive or alloys with higher resistivity, which means they don’t have as little resistance as that top group.
