Solution 1

Sure, I can help with that. The resistance (R) of a wire can be found using the formula:

R = ρL/A

where:

  • R is the resistance,
  • ρ is the resistivity of the material,
  • L is the length of the wire, and
  • A is the cross-sectional area of the wire.

We can rearrange this formula to solve for L:
