Capacitor Bank Definition: A capacitor bank is a collection of multiple capacitors used to store electrical energy and enhance the functionality of electrical power systems. Power Factor Correction: Power factor correction involves adjusting the capacitor bank to optimize the use of electricity, thereby improving the efficiency and reducing costs.

Series capacitor banks have some advantages over shunt capacitor banks, such as:
When capacitors are connected in series, the total capacitance is less than any one of the series capacitors’ individual capacitances. If two or more capacitors are connected in series, the overall effect is that of a single (equivalent) capacitor having the sum total of the plate spacings of the individual capacitors.
The basic formula for calculating the size of a series capacitor bank is: C = 1/ (2πfX) Where, C is the capacitance in farads (F) f is the frequency in hertz (Hz) X is the reactance in ohms (Ω)

(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.
