Question

9. Find the equivalent resistance between A and B.​

Answer 1

Answer:

Option 3) 22/7

Step-by-step explanation:

Let’s take 6ohms and 3ohms as R1 and R2 respectively

As these are connected in parallel

1/R6 = 1/R1 + 1/R2

1/R6 = 1/6 + 1/3

1/R6 = 1/2

R6 = 2 ohms

Let’s take 2,4,8 ohms as R3,R4,R5 respectively

1/R7 = 1/R3 + 1/R4 +1/R5

1/R7 = 1/2 + 1/4 + 1/8

1/R7 = 7/8

R7 = 8/7

As r6 and R7 are connected in series

Total resistance = r6 + R7

= 2+(8/7)

= 22/7
