Q: In the diagram resistance between any two junctions is $R$. Equivalent resistance across terminals $A$ and $B$ is

d $R_{C D}=\frac{1}{\frac{1}{2 R}+\frac{1}{R}}=\frac{2 R}{3}$ Similarly $R_{DB}$ $=\frac{4^{2} R}{3}$ $R_{C B}=\frac{1}{\frac{1}{R}+\frac{1}{\frac{2 R}{3}+\frac{2 R}{3}}} ; R_{C B}=\frac{4 R}{7}$ $R_{A B}=\frac{1}{\frac{1}{R}+\frac{1}{\frac{4 R}{7}+R}} ; R_{A B}=\frac{11 R}{18}$
