A) \[1\,\Omega \]
B) \[3\,\Omega \]
C) \[6\,\Omega \]
D) \[9\,\Omega \]
Correct Answer: B
Solution :
[b] Effective resistance in parallel combination is given by, \[{{R}_{p}}=1\Omega \] So, \[\frac{1}{1}=\frac{1}{3}+\frac{1}{R}+\frac{1}{3}\] Or \[\frac{1}{R}=1-\frac{2}{3}=\frac{1}{3}\] \[\therefore \,\,R=3\Omega \]You need to login to perform this action.
