Resistance, R = ρL / A

where R = Resistance, ρ = constant called Resistivity, L = Length and A = Area,

From the formula, above, the Resistance R would decrease if the length is small.

So from the options, that correspond to:

shorter wires

The length of a wire affects its resistance, and shorter wires would decrease the resistance of wires carrying an electric current.

What is the resistance of a wire?

The resistance of a wire is the opposition to the flow of electric current. The resistance of a wire is determined using the following formula;

R = ρL / A

where;

  • R is the reistance
  • ρ is resistivity
  • L is length of the wire
  • A is area of the wire

Thus, the length of a wire affects its resistance, and shorter wires would decrease the resistance of wires carrying an electric current.
