what would decrease the resistance of wires carrying an electric current?\nshorter wires\nhigher…

Brief Explanations:

The resistance formula for a wire is $R = \rho\frac{l}{A}$, where $R$ is resistance, $\rho$ is resistivity (a property of the material), $l$ is length, and $A$ is cross - sectional area. Resistance is directly proportional to length and inversely proportional to cross - sectional area. Shorter wires have less length ($l$ is smaller), which decreases resistance. Higher temperature usually increases resistivity 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
