Electrolytic Capacitor

Recommended Posts


Hi
Why an Electrolytic Capacitor explode when connected in reverse mannar?
thank you

Hi Walid,
Welcome back. :)

An electrolytic capacitor conducts a high DC current when it is connected with backwards polarity. I think the current causes the electrolyte to quickly get hot and boil which makes steam and an explosion.

Cheap speakers use non-polarized electrolytic capacitors in their passive crossover network to keep the low frequencies out of the tweeters and keep the high frequencies out of the woofer.

Inexpensive audio amplifiers use them to couple audio frequencies.
