Question

what would decrease the resistance of wires carrying an electric current? shorter wires higher - temperature wires darker - colored wires thinner wires

Explanation:

The resistance of a wire is given by the formula $R =
ho\frac{l}{A}$, where $
ho$ is the resistivity of the material, $l$ is the length of the wire, and $A$ is the cross - sectional area. Shorter length ($l$) decreases resistance. Higher temperature usually increases resistivity ($
ho$) and thus resistance. Color of wire has no relation to resistance. Thinner wires have smaller cross - sectional area ($A$) which increases resistance.

Answer:

shorter wires
