    Find the equivalent capacitance of the system shown in figure (31-E8) between the points a and b.
    Figure
    Ans : Capacitors C1 and C2 above and below ab are connected in series and in parallel with C3.
    Thus, the equivalent capacitor between a and b is given by
    `` {C}_{\,\mathrm{\,eq\,}}=\left(\frac{{C}_{1}{C}_{2}}{{C}_{1}+{C}_{2}}+{C}_{3}+\frac{{C}_{1}{C}_{2}}{{C}_{1}+{C}_{2}}\right)``
    `` \Rightarrow {C}_{\,\mathrm{\,eq\,}}={C}_{3}+\frac{2{C}_{1}{C}_{2}}{{C}_{1}+{C}_{2}}``
