Question

find eqivalent resistance across the ends a and b given r = 2ohm​

Answer 1

Answer:

Similarly, R3 ,4 = 1Ω

R5 , 6 = 1Ω

R7 , 8 = 1Ω

Now R1,2 and R3,4 are connected in series

R1 , 2 , 3 , 4 = R1,2 + R3,4 = 1 + 1 = 2Ω

Also , R5,6 and R7,8 are connected in series

R5,6,7,8 = R5,6 + R7,8 = 1 + 1 = 2Ω

Now, equivalent resistance
