low voltage
I have little to add to Dave Tweed''s excellent answer. You wire each strip electrically parallel. If the features of the light allow, you can wire them as a daisy chain, connecting one strip into another strip into another strip. That is not strictly "series", but it is often called that incorrectly.

The resistance of a capacitor to voltage changes happens all the time. The degree of ''resistance to change'' is proportional to the difference between the voltage source and the capacitor voltage. If the voltage in the source is less than the capacitor voltage, the capacitor will provide current to the source.
