In electronics, a choke is an inductor used to block higher-frequency alternating currents (ACs) while passing direct current (DC) and lower-frequency ACs in a circuit. A choke usually consists of a coil of insulated wire often wound on a magnetic core, although some consist of a doughnut-shaped "bead" of … See more Chokes are divided into two broad classes: • Audio frequency chokes (AFC) – designed to block audio and power line frequencies while allowing DC to pass • Radio frequency … See more • Line reactor • Waveguide choke - designed to enhance or inhibit propagation of specific modes in waveguides.
