Explanation / Answer

Rank the resistors in the figure below (A to C) on the basis of thecurrent that flows through them. Rank from largest to smallest. Torank items as equivalent, overlap them. let A=B=C=R A and B are in series so their total resistance=2R now 2R and R are connected in parallel. hence the net resistance=2R*R/3R=2R/3 now current through the circuit i=V/R=3V/2R current passing through A = i*R/3R=3V/2R *R/3R=V/2R as A and B are in series same current passes through them. current through C is 3V/2R-V/2R=V/R hence C A,B or C,B,A as A and B are equal
