CAPACITOR & CAPACITANCE
though the outer case remains relatively cool. Capacitors used within high energy capacitor banks can violently explode when a fault in one capacitor causes sudden dumping of energy stored in the rest of the bank into the failing unit. And, high voltage vacuum capacitors can generate soft X-rays even during normal operation.

Can capacitor burst be dangerous?
Modern capacitors have a safety valve, typically either a scored section of the can, or a specially designed end seal to vent the hot gas/liquid, but ruptures can still be dramatic.An electrolytic can withstand a reverse bias for a short period, but will conduct significant current and not act as a very good capacitor.
