How Long Does It Take a Capacitor to Discharge [1]

The time required to discharge a capacitor depends upon the time period of the capacitor. After 5 time periods, a capacitor will be discharged almost completely
The time period of a capacitor is the product of its capacitance (in farads) and the value of the discharging resistor (in ohms). How Much Times Does It Take a Capacitor to Discharge
After one time period, a fully charged capacitor discharges nearly 37% of its stored charge. So, after 5 time periods, it can be safely assumed that the capacitor is completely discharged for any practical purposes.

Capacitor Charge and Time Constant Calculator [2]

This calculator computes for the capacitor charge time and energy, given the supply voltage and the added series resistance.. This calculator is designed to compute for the value of the energy stored in a capacitor given its capacitance value and the voltage across it
Note that the input capacitance must be in microfarads (μF).. The time constant of a resistor-capacitor series combination is defined as the time it takes for the capacitor to deplete 36.8% (for a discharging circuit) of its charge or the time it takes to reach 63.2% (for a charging circuit) of its maximum charge capacity given that it has no initial charge
Consequently, the cutoff frequency of the circuit is defined by the time constant.. The charging/discharging property of a capacitor made a lot of applications in electrical engineering possible

On large electrolytic caps, like “main-frame” computer grade 100,000uF and TV HV 10uF 25KV doubler Caps, power supplies there is a phenomena like in batteries, known as memory. Short it long enough to discharge the memory effect.
So the rest of this is for educational, technical, and factual values.. In fact some of my grey beard colleagues will remember that caps in storage like this required slow “conditioning” to prevent puncturing the insulation inside so a slow charge up for an hour was recommended before use
However neglect ( <<1x C1 ) in ceramic/plastic caps . This Memory capacitance C2 may be the smaller or much higher so the original voltage is restore but the series resistance R3 is enough so you cant get much current from it but it can give you a jolt if you only short the cap for a zap or split second.

How Long Does A Capacitor Hold Charge? [7]

The amount of time it takes to discharge depends on the capacitance and the current flowing through it.. While capacitors store the charge and release it when needed, but if you put too much charge on them, they get damaged.
