Question

find equivalent resistance between A and B in the combination shown im the figure

​

Answer 1

Answer:

I think it should be 8 ohm

Answer 2

Answer:

12 ohm and 4 ohm are in paralel formation ,

so,

1/R1 + 1R2 = 1/12 + 1/4 ( taking LCM )

1+3/12 = 4/12

1/R = 1/3 ( after simplifying)

R = 3 ohm

The 2 and 5 ohm resistors are in series

= 2+ 5

= 7 ohm

( earlier found above )

7+3

= 10 ohm

ANSWER IS 10 OHM
