Capacitor with bleeder resistor
WebJan 29, 2024 · I would use a 10 gigohm resistor and make sure that it or the series of resistors are rated to at the least 130% of the maximum applied voltage. With only one bleeder resistor, the total voltage for the capacitor network will discharge to below 40 volts in about 10 minutes, but it might leave some individual capacitors in the network charged. WebApr 10, 2024 · sagor1. That tube is a full wave rectifier. Pin 8 would likely go to high voltage capacitor. if resistor is also on pin 8 or what it connects to, odds are it is a bleeder resistor to discharge the capacitor, since it is a high value. 470k would be about right, but not critical in that situation.

They are also used in audio circuits to prevent popping noises …
WebBleeder resistors are sometimes put across capacitors so that you don't have to wait for them to self discharge. This is sometimes done where a capacitor has high voltages applied to it such that when you turn the system off the capacitor will have a diminished or safe voltage on it by the time you can touch it. Webthe X capacitor voltage must drop to 37% within 1s. Based on a 5% tolerance for the discharge resistor and a 20% tolerance for the X capacitor, select an RC time constant …
WebAn electronic apparatus may have large capacitors at high voltage in the power supply section, presenting a shock hazard even when the apparatus is switched off. A “bleeder resistor” is therefore placed across such a capacitor, as shown schematically in Figure 21.53, to bleed the charge from it after the apparatus is off. Why must the ...
