Free QuoteWhen capacitors are connected together in parallel the total or equivalent capacitance, CT in the circuit is equal to the sum of all the individual capacitors added together. This is because the top plate of capacitor, C1 is connected to the top plate of C2 which is connected to the top plate of C3 and so on.
When 4, 5, 6 or even more capacitors are connected together the total capacitance of the circuit CT would still be the sum of all the individual capacitors added together and as we know now, the total capacitance of a parallel circuit is always greater than the highest value capacitor.
Tuning Circuits: Capacitors in series and parallel combinations are used to tune circuits to specific frequencies, as seen in radio receivers. Power Supply Smoothing: Capacitors in parallel are often used in power supplies to smooth out voltage fluctuations.
One important point to remember about parallel connected capacitor circuits, the total capacitance ( CT ) of any two or more capacitors connected together in parallel will always be GREATER than the value of the largest capacitor in the group as we are adding together values.
Total capacitance in parallel Cp = C1 + C2 + C3 + … If a circuit contains a combination of capacitors in series and parallel, identify series and parallel parts, compute their capacitances, and then find the total. If you wish to store a large amount of energy in a capacitor bank, would you connect capacitors in series or parallel?
The parallel combination is equivalent to a single capacitor with the same total charge Q = Q1 +Q2 Q = Q 1 + Q 2 and potential difference V as the combination (Fig. 3b). The equivalent capacitance of the combination, is the same as the capacitance Q/V Q / V of this single equivalent capacitor. So from Eq. (3), Ceq = C1 +C2 C e q = C 1 + C 2
