If the length of a conducting wire is doubled, the resistance of the wire will also double assuming the wire's cross-sectional area remains constant. This is because resistance is directly proportional to the length of the wire according to the formula:

R = ρ * (L/A)

Where:
R = resistance
ρ = resistivity of the material
L = length of the wire
A = cross-sectional area of the wire

Therefore, if the length of the wire is doubled, the resistance will also double, assuming all other factors remain constant.
