- In electronics, a coil of low-resistance wire that acts as an inductor.
Chokes are used to limit the flow of high-frequency alternating
current (AC) in radio circuits or to smooth the waveform of the
direct current from a rectifier. A
familiar choke in domestic use is the "starter" of a fluorescent lighting
- In an internal combustion engine, a choke is a mechanical valve-like
device that reduces the amount of air in the air-fuel mixture in order
to provide a rich enough mixture for the engine to start.
