498. In the schematic of the electrical circuit shown in figure «A» of the illustration, what is the value of the total capacitance, when compared to the value of equal individual capacitors

Two equal capacitors in series have a total capacitance equal to one half the value of a single capacitor. The formula for capacitors in series is 1/C_T = 1/C_1 + 1/C_2, which results in C_T = C/2 when C_1 = C_2 = C.
