What is the effective capacitance between points $\mathrm{X}$ and $\mathrm{Y} ?$
What is the effective capacitance between points $\mathrm{X}$ and $\mathrm{Y} ?$
$8 \mu \mathrm{F}$
$9 \mu \mathrm{F}$
$10 \mu \mathrm{F}$
$12 \mu \mathrm{F}$
Solution
By symmetry $\mathrm{C}_{5}=10 \mu \mathrm{F}$. Capacitor between $\mathrm{B}$ and $\mathrm{C}$ can be removed so, now $C_{e q}=\frac{8 \times 8}{8+8}+\frac{8 \times 8}{8+8}=8 \mu \mathrm{F}$
