Put simply: The large electrolytic capacitor acts as a short for low frequencies.
and the small disc or dipped capacitor acts as a short for high frequencies.

In other words the Impedance/Frequency  characteristics of the two
types of caps are vastly different.

In many products, I see a large electrolytic capacitor in parallel with a
small disc or dipped capacitor.  Why is that done?  Obviously, the pair
does not act as a single large capacitor, or aonly a single one would be
used.  Just how does that arrangement work?
