Bridge capacitor equivalent capacitance

What is the equivalent capacitance of the system of capacitors

As we can see, the capacitances are in series. We two capacitors are in series connection, the reciprocal of the equivalent capacitance is equal to the sum of the reciprocals of the individual capacitances. The means that equivalent capacitance of the given combination is $dfrac{1}{{{C}_{eq}}}=dfrac{1}{2C}+dfrac{1}{2C}$.
