What is a bleeder resistor? And why would you want to use one?

 

this is a standard resistor that is connected in parallel with the output of the higher voltage output of a power supply with the purpose of discharging the power stored in the power supply filter capacitor in the equivalent when the same is put off. for more information about resistors and capacitors, you can get support from here How to select resistor and capacitor components for PCB design? - PCB Design Tutorial - PCBway The blog will also show you how to select the capacitors and resistors.
