Capacitors Basics
How capacitors work. Now that we know what a capacitor is, let''s talk about how it works. When a voltage is applied to a capacitor, it starts charging up, storing electrical energy in the form of electrons on one of the plates. The other plate becomes positively charged to balance things out.

How do smaller capacitors filter out higher frequencies than larger …
I commonly see 0.1 µF used on IC pins for decoupling. I occasionally see 0.01 µF and 0.001 µF capacitors used for filtering out higher frequencies. Is that incorrect, because I thought the impedance If practical capacitors were purely capacitive, then indeed, a larger capacitor would do an even better (or at least "as good") job of filtering …
