Question 3

A metal conductor Y has a resistance.

What is the change in resistance compared to Y for a conductor of the same material that is:

  • longer than Y but has the same cross-sectional area?
  • the same length as Y but has a larger cross-sectional area?
A

Resistance of longer conductor is greater; resistance of conductor with larger cross-sectional area is greater

B

Resistance of longer conductor is greater; resistance of conductor with larger cross-sectional area is smaller

C

Resistance of longer conductor is smaller; resistance of conductor with larger cross-sectional area is greater

D

Resistance of longer conductor is smaller; resistance of conductor with larger cross-sectional area is smaller
