capacitors burn at discharge due to low current-limiting resistor;
This is what I know: the charging of a capacitor from a dc source happens instantaneously. Since there is no series resistor to limit the current, then what actually prevents the current to become infinite and burn the capacitor at charging time? On the opposite is the discharging. If a charged capacitor is shorted, it will burn.

Why does a capacitor fail?
There are several reasons why a capacitor can fail, including: Overvoltage: Exposing a capacitor to a voltage higher than its rated voltage can cause the dielectric material to break down, leading to a short circuit or even a catastrophic failure.
What happens if a capacitor is over rated?
If the capacitor is exposed to voltages beyond its rated value, it risks failure, leading to possible damage to the circuit.
