Question

5. Assertion – metals such as copper and aluminium have high electrical conductivity.
Reasoning – copper has greater conductivity compared to aluminium.

Answer 1

Answer:

Aluminum has 61 percent of the conductivity of copper, but has only 30 percent of the weight of copper. That means that a bare wire of aluminum weighs half as much as a bare wire of copper that has the same electrical resistance. Aluminum is generally more inexpensive when compared to copper conductors.

Answer 2

$\huge\underline\mathtt\red{Answer:}$

Assertion is true but the reason is false.

Because reason supports other statement like if Copper have greater conductivity but Assertion only asked metals have high conductivity so reason could be metals. contain free moving delocalized electrons.
