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.

What voltage should a capacitor be discharged?

Different discharge methods are chosen based on the measured voltage of the capacitor: Less than 10 volts: This voltage is generally considered safe and does not require additional discharge procedures. Between 10 and 99 volts: Although low, this voltage still poses some risk. Use simple tools like a screwdriver for quick discharge in this case.
