Connecting capacitors in series has a couple of important properties that are listed below. It is important that series capacitors always have the same capacitance and maximum voltage value.

Dangers of series capacitors:

Capacitors store energy and therefore a couple of challenges arise that don’t apply to passive components. Even though I use the word danger, the capacitor probably won’t be an actual danger to you as long as it isn’t too high of a value capacitor and you don’t use a lot of voltage. The danger is mostly in damaging the component, which is easy to avoid if you pay close attention.

Video below covers the following circuit.

Fractional capacitance. 2 equal value capacitors in series provides 1/2 the capacitance of the rated value of one of them. 3 in series will be 1/3rd the capacitance of the rated value of one of them. And so on.

Multiple amount of voltage capability. As long as you keep them well balanced, 2 equal value series capacitors can be charged to twice the voltage of the rated value of one of them. 3 equal series capacitors that are well balanced can be charged to 3 times the voltage of their rated value.

Balancing: It is extremely easy for capacitors to charge or discharge unevenly. Take care to make sure that they stay the same voltage.

Polarization: If the capacitors are polarized, then the side marked negative needs to never be more positively charged than the positive side of the capacitor. The negative side should be towards negative terminals/ground of the power source, while the positive side is towards the postive/Vcc terminal.

Series electronics capacitors basics multimeter measured and explained by electronzap



1mA of constant current charging a 1,000µF capacitor will raise its voltage by one volt per second.

Putting another 1,000µF capacitor in series with it, means that both of those capacitors will get 1mA of current, and both of them will raise their voltage by one volt per second. Giving a total of 2V per second.

Thus, the two 1,000µF capacitors in series act like a 500µF capacitor, which changes 2V per second at 1mA of current.
