Question

Q.11 Two wires 1 & 2 of same length & same resistance with area of cross-section A1 and A2 where resistivity R1 & R2 (whereR1 > R2). Which wire is thick?
(a) Wire 1
(b) Wire 2
(c) Wire 1 & Wire 2
(d) None of the above​

Answer 1

Answer:

Wire 2

Explanation:

Because : Thick wire would have much cross section

(Resistance is inversely proportional to cross section)

If cross section would high , resistance would less .

It has been given that R1 > R2

So R2 is less and Hence Answer would be Wire 2
