Meaning and Definition
An electrical resistor connected across the terminals of a power supply or a capacitor to discharge it for safety purposes after the circuit is switched off.
In electronics, a component that provides a discharge path to eliminate dangerous residual charge. It can also refer to a resistor used to draw a small constant current from a voltage source to stabilize its output.

Common Mistakes When Using “bleeder resistor”
- Misspelling as 'bleader resistor'.
- Using it to refer to any resistor, rather than one specifically for discharge/safety.
- Confusing it with a 'pull-down' or 'pull-up' resistor, which have different functions.
FAQ
Frequently Asked Questions
No. While both can drain charge, a bleeder resistor is specifically for safety discharge of high voltage/energy storage components. A pull-down resistor is used in digital logic to define a default low state on an input pin.
Technically yes, but a proper bleeder resistor must be rated for the voltage and power it will dissipate. Its resistance value is calculated to discharge the capacitor to a safe voltage within a required time.
It uses the metaphor of bleeding a fluid. The resistor allows charge to 'bleed off' or leak away slowly and safely, similar to how a controlled bleed valve releases pressure from a system.
In any device with large, high-voltage capacitors that can store a dangerous charge for a long time after being unplugged. Examples include CRT televisions/monitors, microwave ovens, flash units, and tube amplifiers.
An electrical resistor connected across the terminals of a power supply or a capacitor to discharge it for safety purposes after the circuit is switched off.
Bleeder resistor is usually technical / jargon in register.
Bleeder resistor: in British English it is pronounced /ˈbliːdə rɪˈzɪstə/, and in American English it is pronounced /ˈblidər rɪˈzɪstər/. Tap the audio buttons above to hear it.
Learning
Memory Aids
Mnemonic
Think of a 'bleeder' as something that slowly lets fluid out. A 'bleeder resistor' slowly lets electrical charge out (bleeds it off) to make a circuit safe.
Conceptual Metaphor
BLEEDING IS DRAINING / RELEASING (charge is metaphorically treated as a fluid that can be drained away).
