How do you know which caps should be ceramic or electrolytic? I can't seem to wrap my head around which should be which.
Well, generally electrolytic caps are used on power circuits, and for taking lines to ground. Generally ceramic caps are used in audio circuits for blocking DC from inputs and outputs. And you can see them in line with the audio "trail" instead of going to ground or power. Electrolytic are polarized, and work better in power circuits. If you put one where a ceramic one goes, like inline with the audio, there will be a chance of peaks equal in positive and negative on each leg and it can explode or damage the capacitor. Ceramic caps can't generally deal with the power constraints oil based caps like electrolytic can.
