A bleeder resistor is a resistor placed in parallel with a high-voltage supply for the purposes of discharging the energy stored in the power source's filter capacitors or other components that store electrical energy when the equipment is turned off.

Do you have any information about current sense resistors as well?
ReplyDeletehi PETER.. sorry for the late reply. i've been busy lately. Below are some info about your query.

What is a Current Sensing Resistor?
These resistors are used to monitor the current in a circuit and translate the amount of current in that circuit into a voltage that can be easily measured and monitored.
How do They Work?
As stated by Ohm’s Law, there is a voltage drop across any resistance when current is flowing. A current sensing resistor is designed for low resistance so as to minimize power consumption. As a result, the calibrated resistance senses the current flowing through it in the form of a voltage drop, which is detected and monitored by the control circuitry. In summary, current sensing resistors translate current into a voltage that is monitored by the controlled circuitry.
I HOPE THIS INFO ANSWERED YOUR QUERY.
