Which capacitor for DC blocking in audio applications?
Which capacitor (electrolytic, film, ceramic) do you use for DC blocking in audio applications? From what I have seen most people use electrolytic capacitors. But, also from power decoupling theory we know that we need to add a 10uF electrolytic capacitor with a 0.1uF ceramic capacitor for removing the high frequency components.

21.6: DC Circuits Containing Resistors and Capacitors
When you use a flash camera, it takes a few seconds to charge the capacitor that powers the flash. The light flash discharges the capacitor in a tiny fraction of a second. Why does charging take … Exercise (PageIndex{1}) When is the potential difference across
Supercapacitor | Capacitor Types | Capacitor Guide
In comparison, the self-capacitance of the entire planet Earth is only about 710 µF, more than 15 million times less than the capacitance of a supercapacitor. While an ordinary electrostatic capacitor may have a high maximum operating voltage, the typical
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 …
