You can decrease resistance by making the wire in a circuit smaller.

Question

You can decrease resistance by making the wire in a circuit smaller.

True
False

Answer 1

False. Making the wire in a circuit smaller will increase resistance, as smaller wires have less space for electrons to flow through and therefore will impede the flow of current. To decrease resistance, you can increase the diameter and/or decrease the length of the wire.

Answer 2

False.

The resistance of a wire is primarily determined by its length, cross-sectional area, and material. The longer the wire, the greater its resistance. Conversely, the shorter the wire, the lower its resistance. Additionally, the larger the cross-sectional area of the wire, the lower its resistance. Therefore, making the wire smaller would actually increase its resistance.

Answer 3

False. The resistance of a wire in a circuit is influenced by its material and length, not its physical size. To decrease resistance, you can either increase the thickness (cross-sectional area) of the wire or reduce its length. This is based on the fact that resistance is directly proportional to the length of the wire and inversely proportional to the cross-sectional area. By reducing the length or increasing the thickness of the wire, you effectively decrease its resistance.
