New Energy Sources WhatsAppWhich side is the capacitor negative on this board? (IO/10 marking)
The curved plate is always negative and it always refers to a polarized capacitor. While it might be possible to use it to indicate which side should get the outer layer of a film capacitor, I would regard that as needlessly confusing--that would be better served by an annotation in plain english (or whatever language). $endgroup$ –
