Confusion about voltage at negative terminal of capacitor

Now, my understanding was that postive charges accumulate at the positive ("top") plate of the capacitor, setting up an electric field within the capacitor which causes negative charges to accumulate at the bottom plate. Does that mean that the bottom plate of the capacitor will be at -5V eventually (at steady-state).

Capacitor banks are widely used in industrial and commercial settings to ...

How to Wire a Capacitor (6 Steps)

Connect the capacitor''s negative terminal to the terminal of the SPST switch. Connect the switch''s other terminal to the appliance''s negative terminal. If unsure which resistor to use, try one in the range of 10k-100kΩ. It should be large enough to control the capacitor for the required charge. Observe the effect on the appliance.

Polarity

The negative pin of the cap is usually indicated by a "-" marking, and/or a colored strip along the can. They might also have a longer positive leg. Below are 10µF (left) and a 1mF electrolytic capacitors, each of which has a dash symbol to mark the negative leg, as well as a longer positive leg.
