A) \[1.5\,\Omega \]
B) \[10\,\Omega \]
C) \[15\,\Omega \]
D) \[1\,\Omega \]
Correct Answer: B
Solution :
\[r=\left( \frac{{{l}_{1}}-{{l}_{2}}}{{{l}_{2}}} \right)\times R'\]\[=\left( \frac{{{l}_{1}}-2}{2} \right)\times 5\] ... (i) and \[r=\left( \frac{{{l}_{1}}-3}{3} \right)\times 10\] ... (ii) On solving (i) and (ii) r = 10 WYou need to login to perform this action.
