Question

When electricians use wiring for houses they use both copper and rubber. Which do you think is used as a conductor?

Answer 1

Copper

Explanation:

Copper is the best conductor of electricity. As it's resistivity is 16.78 nano-ohms, that is very low. And the other advantage is that it is also a non precious metal i.e. inexpensive. The ductility(ability to bend) of copper is also high that makes him more useful to use as wiring for houses
