Ballast Resistor (Noun)
Meaning
A resistor inserted into a circuit to compensate for changes (as those arising from temperature fluctuations).
Classification
Nouns denoting man-made objects.
Examples
- The engineer installed a ballast resistor in the fluorescent lighting circuit to maintain a stable current flow despite temperature fluctuations.
- To compensate for the changing resistance of the thermistor, a ballast resistor was added to the temperature control circuit.
- A ballast resistor was used in the circuit to balance the resistance and ensure consistent operation over a range of temperatures.
- The designer chose a ballast resistor with a high power rating to handle the current surges in the audio amplifier circuit.
- In the old radio, a ballast resistor was used to stabilize the voltage and prevent overheating of the vacuum tubes.
