Common phenomena of capacitor burning out
18.5 Capacitors and Dielectrics
For a given capacitor, the ratio of the charge stored in the capacitor to the voltage difference between the plates of the capacitor always remains the same. Capacitance is determined by the geometry of the capacitor and the materials that it is made from. For a parallel-plate capacitor with nothing between its plates, the capacitance is given by
11 Signs/Symptoms of a Blown/Bad AC Capacitor
10. Capacitor is Leaking Out a Fluid. Sometimes a bad capacitor will start to leak out the dielectric fluid. Expansion of the fluid (usually due to overheating) can cause the capacitor to rupture and the fluid will leak out. Remember that a bad capacitor can still look good (not swollen and without any fluid leaking out).

Burned wire on ac capacitor common
Ok. Getting warm this season and decided to check the ac to make sure it works. The past couple years I have had the ac not work upon first startup. The first year was a leak in the coil. It just popped when I turned it on and everything leaked out. The second year the unit turned on but no cold air. I replaced the capacitor to no avail.
Types of Capacitors: Definition, Diagram, Working, Uses [PDF]
The types of capacitors are categorized as follows based on polarization: Polarized; Unpolarized; A polarized capacitor, also known as an electrolytic capacitor, is a crucial component in an electronic circuit. These capacitors are used to achieve high capacitive density. Unpolarized capacitors are preferred over fully charged capacitors.
