  4. None of the above

Questions & Step-by-Step Solutions

If two resistors of resistivity 5 x 10^-6 Ω·m are connected in series, what is the total resistivity?
  • Step 1: Understand that resistivity is a property of the material, not the arrangement of resistors.
  • Step 2: Note that both resistors have the same resistivity value of 5 x 10^-6 Ω·m.
  • Step 3: Realize that when resistors are connected in series, the total resistance changes, but the resistivity does not.
  • Step 4: Conclude that the total resistivity remains the same at 5 x 10^-6 Ω·m.
