While this does achieve the goal of discharging the capacitor, it also can damage the capacitor, along with other components on the circuit board, the screwdriver, and you. A filter capacitor in a switch mode power supply. This value yields the time (in seconds) that it takes a capacitor to discharge to 63% of the voltage that is charging it up. Power transfer in the capacitor rises with current then peaks about 0.6T followed by exponential decay, thus Pd of R can be 10% of Ppk, where P p k = V 2 / R Examples 1kV 2uF , E= 2J = 2 watt-sec, R=0.2s/C = 10 k Ppk =100W so choose 10% of Ppk, Pd = 10W, 10 k , >1 kV rating 10kV 0.2uF, E= 10J , R=0.2s/C= 1 M, Ppk=100W, Pd=10W, 1 M >10 kV rating For that matter, when you turn the amp off the caps will discharge through the tubes in the several seconds they're cooling down, as long as you don't put it in standby (if so equipped). Using a screwdriver. All - thanks for your feedback. Brand New. Website#d64833ae354e3ad747029dfb{display:none}. If I don't see an LED at the end of this project I'm going to be very disappointed. The last sentence there is why I don't do it this way anymore. Alternatively, you can bridge the terminals of the capacitor for a few seconds with a high wattage resistor, something like 2.2k ohms, 10 watts will work. By adding more components like an LED, additional resistor and diodes, you introduce more points of failure. It introduces more failure points & possibilty of mistakes. This will be one of the electrical connections to your capacitor. Instead of wire, you can also use a set of insulated probes. Two alligator clips 12 gauge wire Electrical tapes A 50W 20k OHM resistor The steps include: Step 1: Assembling the Required Tool You should remember that a discharging tool is simply a small resistor.

For example a 100uF capacitor charged to 300V discharged through a 10k resistor takes about 3 seconds to reduce the voltage to 15V. Attach one lead to each terminal of the capacitor, the bulb should illuminate. One piece of advice, large caps can have a memory effect, whereby a voltage can reappear on them after being discharged. The words Fender, Telecaster, Stratocaster and the associated headstock designs are registered trademarks of the Fender Musical Instruments Corporation. All opinions remain our own. Powerful capacitors with a sufficiently high charge can shock, burn, injure and even kill you. Especially if you are like me and you have most of what you need already lying around. The wires are connected with the alligator clips to soak the voltage from the capacitor. You can connect a resistor from the non battery side of the switch to the cathode of the LED to obtain a predictable discharge period. Another safe way to discharge a capacitor is through a load, usually a high-voltage resistor. A small value resistor (10-100 ohms) will also work. Just place the tool across the capacitor pins (either way) and wait for few seconds and the voltage inside the capacitor will be discharged by the resistors. Once the battery is on for enough time for the capacitor to be fully charged up to 9 volts, the capacitor cannot retain any more charge. These include: Two lengths of wire.
