This proves that capacitance is lower when capacitors are connected in series. Now place the capacitors in parallel. Take the multimeter probes and place one end on the positive side and one end on the negative. You should now read 2µF, or double the value, because capacitors in parallel add together.
Note - When capacitors are in series, the total capacitance value is always less than the smallest capacitance of the circuit. In other words, when capacitors are in series, the total capicitance decreases. It's always less than any of the values of the capacitors in the circuit. The capacitance doesn't increase in series; it decreases.
In the first branch, containing the 4µF and 2µF capacitors, the series capacitance is 1.33µF. And in the second branch, containing the 3µF and 1µF capaictors, the series capacitance is 0.75µF. Now in total, the circuit has 3 capacitances in parallel, 1.33µF, 0.75µF, and 6µF.
Figure 8.3.1 8.3. 1: (a) Three capacitors are connected in series. The magnitude of the charge on each plate is Q. (b) The network of capacitors in (a) is equivalent to one capacitor that has a smaller capacitance than any of the individual capacitances in (a), and the charge on its plates is Q.
Hence, when two capacitors are connected in series, their equivalent capacitance can be directly calculated by multiplying the two capacitances and then dividing by their sum. Let’s consider another special case, when two capacitors have the same capacitance, i.e., C 1 = C 2 = C. In this case, we get,
The various results obtained in respect of a series combination of capacitors can be summarized as below: (i) All the capacitors connected in series acquire equal charges. (ii) The supply voltage (V) is always equal to the sum of the potential differences established across the capacitors i.e.

First, we can start by finding the series capacitance of the capacitors in series. In the first branch, containing the 4µF and 2µF capacitors, the series capacitance is 1.33µF. And in the second branch, containing the 3µF and 1µF capaictors, the series capacitance is 0.75µF.
Gustav Kirchhoff''s Voltage Law is the second of his fundamental laws we can use for circuit analysis. His voltage law states that for a closed loop series path the algebraic sum of all the voltages around any closed loop in a circuit is equal to zero.This is because a circuit loop is a closed conducting path so no energy is lost.

$begingroup$ If charge +Q leaves the battery anode then charge -Q must leave the cathode because the battery can''t have a net charge. That means the top plate of the top capacitor has a +Q charge and the bottom plate of the bottom capacitor has a -Q charge. But these charges are now attracting/repelling the electrons in the wire between the two capacitors.
