A) \[(\sqrt{3}-1)\]
B) \[(1-\sqrt{3})\]
C) \[(1+\sqrt{3})\]
D) \[(2+\sqrt{3})\]
Correct Answer: C
Solution :
Let equivalent resistance between A and B be R, then equivalent resistance between C and D will also be R. \[{R}'=\frac{R}{R+1}+2=R\] or \[{{R}^{2}}-2R-2=0\] \ \[R=\frac{2\pm \sqrt{4+8}}{2}=\sqrt{3}+1\]You need to login to perform this action.
