Capacitors should always be completely discharged before they are handled or before any work is done on a circuit or equipment which has a charged capacitor. The practice of shorting the capacitor with a screwdriver is not only dangerous from the standpoint of the operator but is quite likely to destroy the capacitor because of the high discharge currents.

Polarised capacitor vs. unpolarised capacitor. Which to use when?
In DC power supply feeds both polarized and non-polarized are used and safe as long as polarized capacitors are inserted correctly and no capacitor is exposed to a voltage beyond its rating. In AC power feeds non-polarized capacitors are mandatory, and if connected to AC mains they need to be X or Y rated for safety reasons.
Capacitor broken off motherboard
Hi All, I''ve just had a nasty experience whilst trying to move one of those £$%^& rotating clips that hold the graphic card in the slot. This things are a pain, they are very stiff and usually break if you try to move them. This happened to me, so I got a pair of long nose pliers and applied a...

Less obvious is the creation of micro-cracks under the visible surface of the capacitor, which propagate along isothermal lines within the component (Figure 2). This form of damage is particularly insidious, since electrical failure may not occur until some time after
What does the Voltage Rating on a Capacitor Mean?
The voltage rating on a capacitor is the maximum amount of voltage that a capacitor can safely be exposed to and can store. Remember that capacitors are storage devices. The main thing you need to know about capacitors is that they store X charge at X voltage; meaning, they hold a certain size charge (1µF, 100µF, 1000µF, etc.) at a certain voltage …

Capacitor Fundamentals: Part 2 – How are Capacitors Used?
After the shot is taken, the capacitor must spend some time recharging before it can be used again. Blocking of DC Signals Another important use of capacitors is to stop direct current (DC) but allow alternating current (AC) from one part of an electronic circuit to another.
Variable Capacitors: Tuning and Adjusting
A variable capacitor, sometimes referred to as a tuning capacitor, is a kind of capacitor in which the capacitance can be mechanically or electrically altered on a regular basis.
