Why shouldn''t electrolytic capacitors be short-circuited?
Electrolytic capacitors may become permanently damaged by excessive peak currents, which will definitely occur during short-circuit events. The reason is that (a) the internal resistance will cause a momentary, but large power dissipation (heat!) and (b) the distribution of the current spike inside the capacitor will not be formed evenly across …

What exactly is a short circuit?
Short circuits can produce very high temperatures due to the high power dissipation in the circuit. If a charged, high-voltage capacitor is short circuited by a thin wire, the resulting huge current and power dissipation will cause the wire to actually explode.
Understanding Short Circuits in Capacitors
The "short circuit" is that short piece of wire that connects the plates of the capacitor. We say: "the capacitor is short circuited". If you have short circuit in some electrical appliance, it means that parts which should be …
