Question

find net resistence​

Answer 1

Answer:

1 ohm

All the parallel connection here can be reduced to single resistors of equivalent resistance 1 ohm

again upper two resistors (1ohm each) are in series to make an equivalent resistance of 2 ohm. And repeat it for lower branch too

now two resistances of 2 ohm each are in parallel to make the final resistance to be 1 ohm
