When 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.
Figure 19.6.2 19.6. 2: (a) Capacitors in parallel. Each is connected directly to the voltage source just as if it were all alone, and so the total capacitance in parallel is just the sum of the individual capacitances. (b) The equivalent capacitor has a larger plate area and can therefore hold more charge than the individual capacitors.
Parallel Combination of Capacitors When capacitors are connected in parallel, the total capacitance is the sum of the individual capacitances, because the effective plate area increases. The calculation of total parallel capacitance is analogous to the calculation of total resistance of a series circuit.
Plate are of the two capacitors are A and a but the plate area of the equivalent capacitance of the parallel combination is the sum of the two A+a. General formula for parallel capacitance The total capacitance of parallel capacitors is found by adding the individual capacitances. CT = C1 + C2 + C3 +………….+ Cn
Since the capacitors are connected in parallel, they all have the same voltage V across their plates. However, each capacitor in the parallel network may store a different charge. To find the equivalent capacitance Cp C p of the parallel network, we note that the total charge Q stored by the network is the sum of all the individual charges:
Polarity should be maintained in the case of polarised capacitors (electrolytic capacitors). Parallel grouping of capacitors is shown below and is analogous to the connection of resistance in parallel or cells in parallel. Parallel Combination of Capacitors
