How to safely discharge high voltage (> 42 V) capacitors?
If you are absolutely sure you will not connect the resistor across the capacitors of a power supply that is still turned on, lower resistor values may be useful for faster discharging. With 330 $Omega$, your discharge current will start at something like 320 V / 330 $Omega$ = 0.97 A, a safe value for most electrolytic capacitors.

How long does a 1K resistor take to discharge a capacitor?
If we use a 1kΩ resistor across the leads of the capacitor, it will discharge in 3s. But the important thing to remember is the power rating of the resistor. To safely discharge the capacitor, the resistor must be rated for at least 2.5W of power dissipation. So, choose a 5W 1kΩ resistor, in this case, to be on the safe side.
How do you connect a capacitor to a resistor?
Connect the Resistor: Connect one end of the resistor to one of the capacitor terminals and the other end to the opposite terminal. This creates a path for the charge to flow out gradually. Wait for Discharge: Leave the resistor connected for a sufficient amount of time to allow the capacitor to discharge.
How to discharge a capacitor?
It’s highly recommended to start the discharge process by using a resistor to bridge the capacitor terminals. This helps to safely release the stored energy gradually before a direct connection, reducing the risk of large sparks and excess heat. Pay close attention to the capacitor during the discharge process.
How to choose a capacitor resistor?
But the important thing to remember is the power rating of the resistor. To safely discharge the capacitor, the resistor must be rated for at least 2.5W of power dissipation. So, choose a 5W 1kΩ resistor, in this case, to be on the safe side. These high-power resistors are usually expensive.
How do you discharge a capacitor with a screwdriver?
Begin Discharging Hold the capacitor securely at its base with one hand while using the other hand to hold the screwdriver.
