A) \[6\,ohm\]
B) \[9\,ohm\]
C) \[12\,ohm\]
D) \[15\,ohm\]
Correct Answer: A
Solution :
Since the given bridge is balanced, hence there will be no current through \[9\Omega \] resistance. This resistance has no effect and must be ignored in the calculations. \[{{R}_{AB}}=\frac{9\times 18}{27}=6\,\Omega \]You need to login to perform this action.
