Question

Find net resistance between A and B.

Answer 1

2 is the answer of the question

Answer 2

Here is your answer

starting from left side in figure

R in 1st branch= 4
resultant R of 1st and 2nd
= 4/2= 2

now, resultant of top branch and 2(above proved)
= 2+2=4
now in parallel
4/2=2

resultant with right branch
=2+2= 4
resultant in parallel
= 4/2 = 2

Hence effective resistance of the circuit is 2ohm
