Question

Three copper wires have their lengths in the
ratio 5 : 3:1 and their masses are in the ratio
1:3:5. Their electrical resistance will be in
the ratio
(1) 5:3 : 1
(2) 1 : 3:5
(3) 125 : 15 : 1
(4) 1 : 15 : 125​

Answer 1

Answer:

5:3:1

Explanation:

because R is directly proportional to length l and it is independent of mass m
