Question

find the equivalent resistance?​

Answer 1

Let's solve from the end(right side)

3 and 9 are in series: 9+3 = 12

now this 12 is in parallel with the 12: 12×12/(12+12) = 6

Now this 6 is in series with the 6 : 6+6 = 12

now this 12 is in parallel with the 12: 12×12/(12+12) = 6

Now this 6 is in parallel with the (series 4 and 2= 6)

So 6 and 6 in parallel : 6×6 / (6+6) = 3

Now this 3 is in series with the 3 : 3+3 = 6

equivalent resistance = 6

Now this 3 is in series with the 3 : 3+3 = 6

equivalent resistance = 6
