Question

out of cu,fe,w,and hg which one will you prefer to use in electrical wire for domestic use​

Answer 1

Answer:

The table of electrical resistivity below contains the values of resistivity for many of the substances widely used in electronics. In particular it includes the resistivity of copper, the resistivity of aluminium, gold and silver.

The electrical resistivity is particularly important because it will determine its electrical performance and hence whether it is suitable for use in many electrical components. For example it will be seen that the resistivity of copper, the resistivity of aluminium and that of silver and gold determines where these metals are used.
