Q: Eight resistances each of resistance $5\,\Omega $ are connected in the circuit as shown in figure. The equivalent resistance between $A$ and $B$ is

a $R^{\prime}=\frac{2 R^{2}}{3 R}$ $R^{\prime}=\frac{2 R}{3}$ $R^{\prime}=\frac{2 R}{3}+2 R$ $R^{\prime}=\frac{8 R}{3}$ $R_{e q}=\frac{2 R \cdot R \cdot 8 R / 3}{2 R^{2}+16 R^{2} / 3+8 R^{2} / 3}$ $R_{eq}=\frac{16 R^{3} / 3}{10 R^{2}}$ $R_{e q}=\frac{8 R}{15}$ $=\frac{8 \times 5}{15}=\frac{8}{3} \Omega$
