Question

the resistivity of a wire depends upon its :(1) length (2)cross section area (3) dimensions (4) material​

Answer 1

Answer:

Allll of them

Explanation:

REASON:- length is directly proportional to resistivity.

Cross section is inversely proportional to resistivity.

Answer 2

Answer:

The formula of resistivity is, resistivity=RA/L

Explanation:

where R stand for resistance and A is Cross section area and L stands for length of the wire and resistivity also depends upon the material of the wire. Hope it's help for you.
