According to Table 1, which of the following materials is the best electrical conductor?

Brass
Copper
Aluminum
Nichrome

Expert Solution

The expression to calculate the resistance is, \(R=\frac{\rho L}{A}\)

So, if we consider L/A to be the same for all conductors,

The conductor with lower \(\rho\) will have a lower resistance, and hence will be the better conductor.

So, Copper with the lowest resistivity is the best conductor.
