Answer:

it depends on area and length

Explanation:

in areal expansion length is negligible so it is negligible for restivity.in case of linear expansion area is negligible for resistivity

Answer:

Explanation:

Resistance of a conductor directly depends upon Length of the wire L

Inversely depends upon Area of Cross section of the conductor 1/A

Nature of material used.

Therefore, R=ρ L/A

Listen, it is not copied from Google and just understand the concept I am going to tell now.

As R is directly proportional to L, the R will increase when L increases. For example, if L is doubled, R will also double.

As R is inversely proportional to A, i.e., R = 1/A, the R will decreases when A increases. For example, if A is doubled, R will be halved.

Hope it helps...

Mark it as brainliest if you are satisfied with the answer! :)
