why do you need to add capacitors in both circuits???

Which circuits?

Re: capacitor

Capacitors usually carry an alternating signal or current and block a direct one, and they can store energy. So if you need to do one or more of those things, that is probably a good reason to add a capacitor.

(You might get a better answer if you tell us which circuits and which capacitors you are thinking about !)
