Learn More$begingroup$ @ddewaele: the metal case is the negative terminal of the capacitor - probably ground in most circuits. The metal case is usually exposed on the top of the capacitor - the bit you exposed on the side is part of the same can. If you just touch the case, you won''t get a shock, but if you touch the two terminals, or the case and some …
