Industry Why decoupling capacitors used for power rails should be very
As a board designer, you can not do anything about it. So, to remove this issue on the board level, which is caused by parasitic inductance of trace & plane, we add a decoupling capacitor to provide a local path of voltage & ground. During fast switching, the capacitor acts as a decoupling element to reduce the drop across parasitic inductance.

Don''t do anything like this. Mains voltage is not a toy and it''s not for tinkering. Everything that touches mains voltage should be UL/TUV/etc.* listed as mains equipment and installed according to its labeling and instructions. Bare components from the electronics supply are not equipment: they lack labeling and instructions for use in mains wiring, and cannot be so used.
