In the given circuit, it is observed that the current I is independent of the value of the resistance R6. Then the resistance values must satisfy [IIT-JEE (Screening) 2001]

\[{{R}_{1}}{{R}_{3}}={{R}_{2}}{{R}_{4}}={{R}_{5}}{{R}_{6}}\]

\[{{R}_{1}}{{R}_{2}}{{R}_{5}}={{R}_{3}}{{R}_{4}}{{R}_{6}}\]

\[\frac{1}{{{R}_{5}}}+\frac{1}{{{R}_{6}}}\]\[=\frac{1}{{{R}_{1}}+{{R}_{2}}}+\frac{1}{{{R}_{3}}+{{R}_{4}}}\]

\[{{R}_{1}}{{R}_{4}}={{R}_{2}}{{R}_{3}}\]

In the given circuit, it is observed that the current I is independent
