Generally speaking, you should always replace like-for-like when it comes to capacitors – meaning if your capacitor has a capacitance rating of 10μF, you should select a new one with the same value. However, there are times where it may be necessary to replace with a higher or lower capacitance rating.
So using the above formula, the total capacitance is 1.33µF. 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 higher the capacitance rating, the more energy that can be stored. Generally speaking, you should always replace like-for-like when it comes to capacitors – meaning if your capacitor has a capacitance rating of 10μF, you should select a new one with the same value.
There are different types of representations for the voltage rating of these capacitors. Sometimes it is written clearly on the enclosure of the capacitor with its unit. For some disk capacitors, it is represented by a single underline after the capacitance value. This underline shows 100 V as the maximum working voltage.
This isn't important in all circuits, but you may need to pay attention to this if you require a precise capacitor value. For example, a capacitor labeled "6000uF +50%/-70%" could actually have a capacitance as high as 6000uF + (6000 * 0.5) = 9000uF, or as low as 6000 uF - (6000uF * 0.7) = 1800uF.
Though there are few cases to install a capacitor in series. In my designs, I am not allowing to a voltage stress of more than 75%. This means, if the actual circuit voltage is 10V, the minimum capacitor voltage I will select is 13.33V (10V/0.75). However, there is no such voltage. So, I will go to the next higher level that is 16V.
