Question

which will have more resistance,athin aluminium wire or a long copper wire of equal thickness. (2 marks)​

Answer 1

Answer:

athin aluminium wire

Explanation:

A piece of thin wire has higher resistance than a piece of thicker wire with the same length, which means that it's harder for electric current to move through it. Using a longer wire will also increase resistance.

Answer 2

Answer:

The resistance of a thin wire is greater than the resistance of a thick wire because a thin wire has fewer electrons to carry the current. The relationship between resistance and the area of the cross section of a wire is inversely proportional.
