Question

find the equivalent resistance between a and b​

Answer 1

Answer:

BY OBSERVATION 3 ohm and 6 ohm are in parallel

so (R)eq=2 ohm,

similarly      2 ohm and 8 ohm are in series now

             so equivalent resistance=10 ohm

similarly ,            10 ohm and 30 ohm are in parallel

                             hence >>>>equivalent resistance=15/2 ohm

so resistance between A and B be

                       (R)equivalent=15/2 ohm

I hope it helps.
