Question

A given length of a wire is doubled on itself.By what factor does the resistance of the wire changes?

Answer 1

Answer:

Resistance is directly proportional to the length of the conductor

R = ρ*L/A

So for the given conductor Resistance will double if the length is doubled.

R = Resistance

ρ = constsnt

Resistance is directly proportional to the length of the conductor

L = length

and inversely proportional to the area of cross-section of the conductor

A

as
