Ballast Resistor
Definition: A ballast resistor is an electrical device that limits the current flow in an electric circuit, particularly in automotive ignition systems.
Senses:
- Electrical Component: A type of resistor used to stabilize and reduce the voltage across a circuit, usually employed in automotive ignition systems.
- Automotive Ignition System: A component in the ignition system of a vehicle that helps control the current flow, thus protecting various parts of the system from damage.
Sample Sentences:
- The ballast resistor in the car's ignition system prevents excessive current from damaging the electronic components.
- When the engine misfires, it could be due to a faulty ballast resistor that disrupts the ignition spark.
- Older vehicles often require a ballast resistor to regulate the voltage and prevent overheating of the ignition coil.
