Question

v) Masses of three pieces of wires made of
the same metal are in the ratio 1:3:5 and
their lengths are in the ratio 5:3:1. The
ratios of their resistances are
(B) 5:3:1 0
(C) 1:15:125 (D) 125:15:1
(A) 1:3:5​

Answer 1

Answer:

5:3:1

Explanation:

Resistance, R is directly proportional to the the length and inversely proportional to its area

Resistance does not affect by mass ratio hence the ratio of their resistances are same as their lengths

I.e., 5:3:1
