What is Bleeder Resistor and where it is used? Bleeder resistors are standard high value resistors which are used to discharge the capacitor in filter circuit. The discharging of the capacitors is really important because even if the power supply is OFF, a charged capacitor can give a shock to anybody. So it is really essential to add a bleeder resistor to avoid any mishaps. It also have other applications but the main… |
