Intuitively, why does putting capacitors in series decrease the equivalent capacitance?
(Indeed this value is named "elastance" today. Thanks Alfred Centauri for your comment.) If they had done this, the "capacitance" (which would be $frac {U}{Q}$) of capacitors in series would increase and not decrease!

19.5: Capacitors and Dielectrics
The unit of capacitance is the farad (F), named for Michael Faraday (1791–1867), an English scientist who contributed to the fields of electromagnetism and electrochemistry. Since capacitance is charge per unit voltage, we see that a farad is a coulomb per volt, or
Half Wave Rectifier with Capacitor Filter | Capacitor Polarity
The standard-value capacitors are typically available with +20% tolerance. In the case of capacitors greater than 10 pF, the tolerance is often listed as -10% +50%. This means that a 100 μF capacitor might have a capacitance as low as 90 μF, or as high as 150

5.15: Changing the Distance Between the Plates of a Capacitor
No headers If you gradually increase the distance between the plates of a capacitor (although always keeping it sufficiently small so that the field is uniform) does the intensity of the field change or does it stay the same? If the former, does it increase or decrease?
Why does the distance between the plates of a capacitor affect its capacitance?
Why does the capacitance of a capacitor increase when its plates are closer in distance to each other? $begingroup$ true, and nice graphic, but let''s play devil''s advocate: just because for a given charge Q, the electric field is stronger when the plates are closer doesn''t give you any intuitive indication that the voltage is stronger or weaker …

Fundamentals | Capacitor Guide
The capacitance value of a capacitor is represented by the formula: where C is the capacitance, Q is the amount of charge stored, and V is the voltage between the two electrodes. One plate equals the amount of charge on the other plate of a capacitor in real life circuits the amount of charge on, but these two charges are of different signs.
electricity
This means that a capacitor with a larger capacitance can store more charge than a capacitor with smaller capacitance, for a fixed voltage across the capacitor leads. The voltage across a capacitor leads is very analogous to water pressure in a pipe, as higher voltage leads to a higher flow rate of electrons (electric current) in a wire for a …
How does a run capacitor value affect the motor?
Start capacitors will typically have a much higher capacitance rating than run capacitors (100 to 1600 µF vs. 5-100 µF). This is because they need to be able to store more charge in order to provide enough power for the motor''s startup phase.
