    i have tried to find the effective resistance between node D and node E .. by making (R4+R5+R2)//R6 :eek:
    but i think this is wrong .. do u guys have any other approach to solve this problem.. i wanna know how to find the effective resistance between node D and node E.. :D

    One must redraw the circuit so the solution becomes more intuitive. Notice there are three vertical branches in parallel. Move the R5,R6 branch with node 'd' to the far right. Focus on the R3 branch in parallel with the R4,R2 branch and reduce that to a single resistance which is in series with R5 and then in parallel with R6. R1 makes no contribution to the resistance from 'd' to 'e'.
