What would decrease the resistance of wires carrying an electric current?
A. shorter wires
B. higher-temperature wires
C. darker-colored wires
D. thinner wires

Asked by angelinecaridadromer

Answer (2)

The resistance of wires decreases with shorter lengths, as described by the formula R = ρ(L/A). Higher temperatures and thinner wire diameters actually increase resistance. Consequently, the correct answer is shorter wires, which reduce the overall resistance of the wire. ;

The resistance of wires decreases with shorter lengths, as indicated by the formula R = ρ(L/A), where shortening the wire reduces L. Higher temperatures and thinner diameters actually increase resistance. Therefore, the correct answer to the question is A. shorter wires.
