A) 3.23\[\Omega \]
B) 4.23\[\Omega \]
C) 6.32\[\Omega \]
D) infinite
Correct Answer: A
Solution :
Suppose the equivalent resistance between points P and Q is R. \[R=\frac{2R}{2+R}+2\] \[{{R}^{2}}-2R-4=0\] \[R=1\pm \sqrt{5}\] Taking +ve sign. \[R=\sqrt{5}+1=3.23\,\Omega \]You need to login to perform this action.
