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

• Brass
• Copper
• Aluminum
• Nichrome

## Solutions

##### 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.
