Answer» in 3.20a1 OHM and 2 ohm resistance is in seriesso EFFECTIVE resistance is 3 ohmNow 3ohm resistance is in PARALLEL with 1.5 ohm resistance so effective resistance is 1 ohmin 3.20 bresistance on ac and cb LINE are in series so effective resistance = 5ohmresistance on ad and bd line is ALSO in series so effective resistance = 5 ohm now three resistance are left 5ohm 1 ohm and 5ohm all are in parallel so effective resistance = 1/5+ 1+ 1/5=7/5= 1/RR= 5/7= 0.71 ohm |
