Derive the ratio between original and new resistance when a wire is tripled on itself?
Asked by bharadwajlucky26 | 14 Sep, 2018, 04:37: PM
answered-by-expert Expert Answer
Resistance R = ρ×(L/A) ..............(1)
where ρ is the resistivity of material, L is length and A is area of cross section.
 
Resistance is directly proportional to length. When length is tripled, assuming area of cross section remains constant,
resistance also tripled
