Question

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

Explanation:

Resistance of a wire is given by \( R =
ho \frac{L}{A} \), where \(
ho \) is resistivity, \( L \) is length, and \( A \) is cross-sectional area. Shorter length (\( L \)) reduces resistance. Higher temperature increases resistivity (thus resistance), thinner wires reduce cross-sectional area (increase resistance), and color has no effect on resistance.

Answer:

shorter wires
