In DC power sources, you will see large capacitors in parallel with the output used to filter the DC voltage output. In an "ideal" DC voltage source (like a fully charged car battery), putting capacitors in parallel with the battery terminals will initially change the total circuit current until the capacitor is fully charged wherein the current drawn by the capacitor is …

The same situation occurs if you took two ideal voltage sources and connected them in parallel. Of course, in the real world the wires are not ideal and they have some finite resistance. This resistance limits the maximum current when the capacitors are connected. Furthermore, since there is a "resistor" element between them the capacitors are ...
