Question

Because aluminum wire is not as good a conductor as copper, a larger gauge must be used. ___ instead of 14, with other wire suitably increased

Answer 1

Aluminium wire requires a larger gauge than copper wire due to its lower conductivity. While aluminium wire is cheaper, it has higher thermal expansion and oxidation concerns. Special techniques are required when working with aluminium wires.

Step-by-step explanation:

When using aluminium wire, a larger gauge must be used because aluminium is not as good a conductor as copper. The larger gauge compensates for the lower conductivity of aluminium, ensuring that the wire can carry the required current. For example, instead of using a 14-gauge copper wire, a larger gauge aluminium wire would need to be used.

It's important to note that while aluminium wire may have lower conductivity compared to copper, it is still within acceptable levels and offers cost savings. However, there are some concerns when using aluminium wire. It has a higher rate of thermal expansion than copper, which can lead to loose connections and potential fire hazards. Additionally, the oxidation of aluminium can cause problems, so special techniques must be used when working with aluminium wires.
