Fig.1 shows the given network of resistors. When we find resistance between the points A and D ,

Resistances between G and B and also between C and F are isolated .

Hence resistors between G and B and also between C and F are removed as shown in fig.2 .

If we see in fig.2 , between the point E and H , two 20 Ω resistors are in parallel that gives equivalent resistance 10 Ω

between E and H .

Hence we get , as shown in fig.3 , three 10 Ω resistors are in series that gives 30 Ω as equivalent resistance between A and D
