(b) Q = C eq V. Substituting the values, we get. Q = 2 μF × 18 V = 36 μ C. V 1 = Q/C 1 = 36 μ C/ 6 μ F = 6 V. V 2 = Q/C 2 = 36 μ C/ 3 μ F = 12 V (c) When capacitors are connected in series, the magnitude of charge Q on each capacitor is the same.The charge on each capacitor will equal the charge supplied by the battery. Thus, each capacitor will have a charge of 36 μC.
The Mechanically Commutated Series Capacitors (MCSC), also called Fixed Series Compensation (FSC) is the most common series compensation equipment currently installed in power systems [31,32]. The MCSC scheme is shown in Figure 5 . The capacitor banks consist of parallel and series arrays of AC capacitors, along with other auxiliary equipment.

So, the total capacitance of capacitors connected in parallel is equal to the sum of their values. How to Calculate Capacitors in Series. When capacitors are connected in series, on the other hand, the total capacitance is less than the sum of the capacitor values. In fact, it''s equal to less than any single capacitor value in the circuit.
