The right hand side of the capacitor is at 1.8 volts. The Left hand side of the capacitor is probably less than 1.8 volts due to the load the microphone presents. Therefore, the right hand side is probably more positive than the left hand side. The capacitor can be connected with the opposite polarity, but it will not function as it was designed to for long, as the dielectric film will deteriorate and possibly the foil plates will short circuit.Why the polarity of the 1U clectrolyte in this circuit is this?Why can't be tied with the other polarity?
I am a electronic new man.Can you explain how to get below corresponding frequency of the capacitor?The 1uF capacitor is so big that it produces a cutoff frequency of 6Hz which is stupid.
Use a 330nF (0.33uF) film capacitor for 18Hz or 220nF (0.22uF) for 27Hz which does not have polarity.
