The discharge of 0.25 J of stored energy to the human body can provide a heavy shock, and 10 J can be fatal. Therefore one of the most critical components of the capacitor banks is the high-voltage discharge resistor, which reduces the residual voltage of the capacitor to a safe working level at turn off.

A capacitor is a device used to store electrical charge and electrical energy. It consists of at least two electrical conductors separated by a distance. (Note that such electrical conductors are sometimes referred to as "electrodes," but more correctly, they are "capacitor plates.") The space between capacitors may simply be a vacuum ...

Fortunately, this capacitor discharge calculator makes this step a lot easier. You will need to know the capacitance, initial charge voltage placed on the capacitor, safety threshold voltage (voltage at which the capacitor is considered safely discharged), and either the resistor value or the discharge time you want to achieve.
A capacitor is a passive electronic device that stores electric charge. Ceramic capacitors consist of two or more alternating layers of ceramic material as the dielectric and metal layers acting as the non-polarized electrodes. Applications include automotive, bypass, decoupling, filtering, RF, and ESD protection.

Therefore, it is safe to say that the time it takes for a capacitor to discharge is 5 time constants. To calculate the time constant of a capacitor, the formula is τ=RC. This value yields the time (in seconds) that it takes a capacitor to discharge to 63% of the voltage that is charging it up.
If you get a meter with a "LoZ" function, that can discharge the cap and can also simultaneously show you directly on the display that you have successfully discharged the capacitor, and it''s also designed to be safe if you were to accidentally try to discharge a capacitor that is still externally powered.
How to Discharge a Capacitor. To discharge a capacitor, unplug the device from its power source and desolder the capacitor from the circuit. Connect each capacitor terminal to each end of a resistor rated at 2k ohms using wires with alligator clips. Wait for 10 seconds for a 1000µF capacitor to discharge.
