resistance in parallel = 1
------------------------------------
1/12 +1/12+1/12+1/12
3 ohm
now three such combinations are in series
:.total resistance is 3 ohm + 3 ohm +3 ohm = 9 ohm

1/12 +1/12+1/12+1/12
3 ohm
now three such combinations are in series
:.total resistance is 3 ohm + 3 ohm +3 ohm = 9 ohm
