Guidelines for determining shock hazard of capacitors
$begingroup$ As a general rule of thumb, before sticking your hands in a circuit with potentially charged capacitors, especially power electronics like audio amplifiers and televisions. It is a good idea to short capacitors across a (largish) bleedoff resistor to discharge them. Sometimes there is a bleedoff path already designed for the larger capacitors but I never bet on it.

What is the easiest way to blow up electrolytic capacitors?
The problem with electrolytic capacitors is that the insulating film is formed by applying voltage. They''ll only blow up if you apply it fast enough that the current flow generates a ton of heat and boils the electrolyte. Reverse bias voltage is the easiest way I think. If you''re trying to make them blow, the ones without vents are the most

Hook this up and once the bulb is no longer lit, the capacitor is discharged. Again, you always want to measure the voltage after it''s supposedly discharged just to be safe.
6 Frequently Asked Questions about “What is the safest way to make capacitors ”
Should I worry about a small capacitor?
With small capacitors up to 1 mF, there is little to worry about. I suppose it's a good idea to make sure they are discharged before plugging them in where the voltage that could be on the cap could damage something, but this is something not generally worried about until you get to some real energies or high voltages.
How do you discharge a capacitor safely?
Cheap, easy, safe. The energy in any charged capacitor is equal to one-half E-squared C. To discharge a capacitor safely, make the discharge resistance high enough that the RC time-constant is equal to about one second. Example: A 500uF capacitor charged to 500V contains 62.5j energy, enough to blow a hole in a beer can.
How to choose a capacitor?

High voltage capacitor may catastrophically fail when subjected tovoltages or currents beyond their ratin losive rupture than rectangular cases due to n inability to easily expand under
Should a capacitor be shorted if it's already discharged?
The rate of discharge depends more heavily on the associated circuitry and less on the capacitors themselves. So best case, they are already discharged. Otherwise, shorting them should be fine, even at that high of voltage, they are only storing about a third of a Joule, so really not that much.
Can a capacitor be charged if turned off?
Even after being turned off for a relatively long period of time, they can still be charged with potentially lethal high voltages. The same applies to all system components and devices which have an electrically conduc-tive connection to the capacitor.
