b]1. The problem statement, all variables and given/known data[/b] Find the total resistance of this complex combination of resistors. [ 2. Relevant equations R(total)= (Rr)/(R+r) 3. The attempt at a solution resistance of r(2) and r(3) = 20Ω resistance of the combination of r(1) and the resultant 20 Ω(ie r(2) and r(3) ) = 20/3 resistance of r(3) and r(5) = 20Ω resistance of te combination of r(4) and the resultant 20 (ie r(3) and r(5) ) = 20/3 I can't deduce and answer from the above (correct) results.
