The Attempt at a Solution


I tried checking if I could use wye-delta transformation. There seems to be no parallel connections between the resistors. Please do help. Thank you

Hi anning, Welcome to Physics Forums.

You might use Δ-Y transformations for Rah [STRIKE]and Rbc[/STRIKE] (the others can be reduced via the usual serial/parallel reductions). You could also first reduce what you can and then stick a voltage source across the terminals in question and solve for the current using KCL, KVL, or other analysis methods. Then Ohm's Law yields R = V/I.
