What is the mechanism for capacitor explosion? [closed]
The electrolyte in an aluminum electrolytic capacitor is conductive, but a thin layer of aluminum oxide on the anode acts as a dielectric. Applying more than about 1.6V of reverse voltage strips the dielectric of its oxygen atoms causing the capacitor to become a near short circuit.
