Why does a capacitor discharge slowly?
Not exactly. The voltage v(t) across the capacitor decays with the time constant RC because the internal resistance of the DVM is across the capacitor when it is measuring the capacitor voltage. The time constant is RC, so a bigger capacitance means that the capacitor voltage takes longer to decay towards zero.

Do flash capacitors discharge over time?
Since the insulation is not 100% effective all capacitors will "leak" charge (discharge) over time. How long depends how efficient the insulation is. One week is probably not enough time to discharge the capacitor unless it is very old. It is common safety protocol to never assume the capacitor is discharged.

6 FAQs about [What to do if the capacitor is not discharged]
How do you discharge a capacitor?
You can discharge a capacitor using a tool specifically designed for the purpose, like a discharge resistor. This tool helps to safely release the stored electrical charge in the capacitor without causing damage. If you don’t have a discharge tool, you can use a well-insulated screwdriver with a metal shaft.
Can you discharge a capacitor with a screwdriver?
It’s often safe to discharge a capacitor using a common insulated screwdriver; however, it is usually a good idea to put together a capacitor discharge tool and use that for electronics with larger capacitors such as household appliances. Start by checking for a charge in your capacitor, then choose a method to discharge it if needed.
Should you discharge a capacitor if it reads 10 volts?
Generally speaking, a charge of greater than 10 volts is considered dangerous enough to shock you. If the capacitor reads as having fewer than 10 volts, you don’t need to discharge it. If the capacitor reads anywhere between 10 and 99 volts, discharge it with a screwdriver.
How do you discharge a capacitor without damaging a motherboard?
To safely discharge the capacitor without damaging the motherboard, desolder it from its position. Be careful not to short the two terminals (bridging the anode and cathode terminals) of the capacitor with your soldering iron, and also make sure you don’t touch these terminals with your bare hands.
How do you discharge a high-capacity or high-voltage capacitor?
For high-capacity or high-voltage capacitors, it’s best to use a discharge tool with a resistor instead of a direct short to reduce the risk of sparks and potential capacitor damage. At any stage of the discharge process, avoid touching the capacitor’s terminals until you’re certain it has been fully discharged.
How do you discharge a 1000 ohm capacitor?
Always adhere to safety precautions while performing the discharge. 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.
