A) 3/5
B) 2
C) 6/5
D) 3
Correct Answer: C
Solution :
If resistances are \[{{R}_{1}}\] and \[{{R}_{2}}\] then \[\frac{{{R}_{1}}{{R}_{2}}}{{{R}_{1}}+{{R}_{2}}}=\frac{6}{8}\] ?..(i) Suppose \[{{R}_{2}}\] is broken then \[{{R}_{1}}=2\Omega \] ?..(ii) On solving equations (i) and (ii) we get \[{{R}_{2}}=6/5\,\Omega \]You need to login to perform this action.
