I was making a project in which I had to use a 2.2uF electrolytic capacitor in series with a microphone and weirdly, the circuit works even if I toggle the polarity of the capacitor, that is the capacitor can be inserted in either polarity to make the circuit work.
Why does this happen? What are the criteria for doing so intentionally? Additionally, if I am to substitute a ceramic capacitor with an electrolytic capacitor, in what polarity should the capacitor be inserted?
This schematic is based on the manufacturer's schematic, in which also, a ceramic capacitor of 2.2uF is used.
This question is referring to the MIC portion of the schematic only.
