SIR PLEASE HELP ME

1 and 2 are in series. (1,2) and 3 are in parallel.

4 and 5 are in series. (4,5) and 6 are in parallel.

Proceed to get the resistance across AD as 19R/11. Take CD as having no resistance [application of wheatstone bridge.]

Try out the second one similarly!

Since you are not replying, I take it for granted that you are acquinted with the star-delta coversion

This was the given diagram:

using star delta transformation, the figure reduces to:

Now we can easily calculate equivalent resistance across AB..........I am trying to figure out the other part; tell me if this solution isn't clear
