Answer:
A decrease in length, or the use of a material with lower resistivity, or an increase in the cross-sectional area of the wire
Explanation:
The resistance of a wire is given by
[tex]R=\frac{\rho L}{A}[/tex]
where
[tex]\rho[/tex] is the resistivity of the material of the wire
L is the length of the wire
A is the cross-sectional area
We see that:
R is directly proportional to [tex]\rho[/tex] and L - therefore if we decrease one of these two, the resistance of the wire will decrease too
R is inversely proportional to A - therefore if the increase the cross-sectional area, the resistance of the wire will decrease
