bleeder resistor

[′blēd·ər ri′zis·tər]
(electricity)
A resistor connected across a power pack or other voltage source to improve voltage regulation by drawing a fixed current value continuously; also used to dissipate the charge remaining in filter capacitors when equipment is turned off.

Care should be taken to balance the intermediate voltage between the capacitors, usually with so-called bleeder resistors.
Additional safety is provided by bleeder resistors which are installed with the filters in order to prevent electrical shock due to accidental discharge of filter capacitors while power is disconnected.
