Question

List the applications of AF and RF chokes​

Answer 1

Answer:

For radio frequencies, air chokes are used since a low inductance is sufficient. These are called radio frequency (R. F) or high frequency (H.F) chokes and are used in wireless receiver circuits. Choke coils can be commonly seen in fluorescent tubes which work on alternating currents.

Answer 2

Answer:

Chokes are widely used in the field of electronics to block higher-frequency while passing direct current and lower frequency of alternating current in an electrical circuit. AF and RF are used for building a complete electronic circuit.

Explanation:

Both AF (audio frequency) and RF (radio frequency) chokes are designed to pass DC and block audio and radio frequencies.

AF chokes typically have ferromagnetic or iron core coils. It has several hundred turns on an iron core to provide high inductance values.

Applications:

1) Used as filter chokes in radio and television receivers

2) Used as modulating chokes in transmitters and in direct motor controllers.

RF chokes either have air chokes or ferrite cores are used to built them which increases inductance of an electronic device.

Applications:

1) Used for eliminating digital RF noise.

2) Used in wireless receiver circuits and to prevent flow of RF current.
