<human>: Q: What is one type of metal which the conducting plates in electrolytic capacitors are commonly made of?
 A: Electrolytic capacitors will self-degrade if unused for a period (around a year), and when full power is applied may short circuit, permanently damaging the capacitor and usually blowing a fuse or causing failure of rectifier diodes (for instance, in older equipment, arcing in rectifier tubes).
