hey since its the same wire the resistivities in both instances are the same so get 2 equations for resistivity equalize them and get the value for resistance . I got it as * ohms

2. Rushwr

$\rho = \frac{ RA }{ L }$

3. Rushwr

$\frac{ 2A }{ L } = \frac{ RA }{ 4L }$

=2Ω*(2)*(2) =8Ω

thank you! and is thats the correct answer and did I show the work correctly?

6. Rushwr

yeah !
