Inductors are given names tied to their applications, eg:
- Choke / RFC, to allow DC but block AC current
- Ballast, to provide high voltage kick to start flourescent lamps
- Reactor / Saturable reactor
- Coil / Tesla Coil / Ignition Coil
- Transformer / Auto transformer, two or more inductances
- Antenna, even a rado antenna can exhibit inductance at certain frequencies.
Units Of Measurement
The modern day unit of measurement for an inductor is the "Henry".
