8.2: Capacitance and Capacitors
For large capacitors, the capacitance value and voltage rating are usually printed directly on the case. Some capacitors use "MFD" which stands for "microfarads".

Series and Parallel Capacitors | Capacitors | Electronics Textbook
When capacitors are connected in series, the total capacitance is less than any one of the series capacitors'' individual capacitances. If two or more capacitors are connected in series, the overall effect is that of a single (equivalent) capacitor having the sum total of the plate spacings of the individual capacitors.
