What happens if you put a capacitor in the wrong direction for a
When I connected it to my circuit I put it in the wrong way. After a few seconds I realized my mistake and switch off the circuit. I want to know if any damage have been done to the capacitor. It is not bulging and it did not explode. Edit it is applied to a 13v 10 amp max supply. It is a aluminum Electrolytic capacitor Panasonic.

Polarized capacitors and reverse breakdown
In general, polarized aluminium electrolytic capacitors can handle about 2 V of reverse voltage. Apply more reverse voltage and they will start to conduct DC. Apply a lot more than 2 V reverse voltage and they will start to conduct a lot of direct current, dissipate a lot of power, become very hot and explode.

In this wrong wiring connection, there is positive voltage across the electrolytic cathode and the negative voltage appears across the oxide layer.
Do electrolytic capacitors explode?
When it comes to a capacitor exploding, the electrolytic capacitor is the most likely type to cause a spectacle compared to its counterparts. Other capacitors will not explode, but rather burn, crack, pop or smoke. The main reason why an electrolytic capacitor might explode is due to its construction.
What causes a capacitor to explode?
The next factor that might cause a capacitor to explode is Over voltage. A capacitor is designed to hold a certain amount of capacitance as well as withstand certain amounts of voltages and currents. The voltage of a capacitor is usually displayed on the outside of its packaging.
Can polarized capacitors damage a capacitor?
Polarized capacitors, such as Electrolytic Capacitors, are not damaged when connected in reverse polarity during AC operation. They are mainly used in smoothing out ripples in DC and are polarized and large. The AC switches direction and cannot damage the capacitors because they are not polarized in AC.
