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

Answer:

shorter wires
