In electronics, a choke is an inductor used to block higher-frequency alternating currents (AC) 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 ferrite bead strung on a wire.
Jan 26, 2021 · How and where it is used. Choke coil contains inductor and resistor, How both of them worked. Choke coil is a part of syllabus for class 12 students, Bsc physics students as well as...
Choke inductor coils (sometimes called radiofrequency chokes) are specific types of inductors engineered for signal filtering properties – primarily, passing DC current while filtering out AC current interference.
Mar 22, 2023 · A choke coil, also known as an inductor or reactor, is a passive electronic component that is used to block high-frequency alternating current (AC) while allowing direct current (DC) to pass through. It consists of a coil of wire wound around a ferromagnetic core.
A choke inductor, also commonly referred to as a choke coil inductor or simply a choke, is a passive electronic component that acts like a gatekeeper for electrical current. Unlike its cousin, the resistor, which dissipates energy as heat, a choke inductor manipulates the current flow based on its frequency.

Nov 10, 2017 · Choke coils used in fluorescent tube generates a transient voltage across the tube to make it conductive as breakdown voltage for gas (mercury vapour and argon, xenon, neon, or krypton) inside the tube is higher than the system voltage.
A choke is a wound coil generally used for smoothing or filtering the outputs from rectifying circuits. Impedance of choke increases with increase in frequency. Choke or coil is also used for RF filtering.
Oct 23, 2022 · A choke coil is simply an inductor with large inductance that is used to reduce the current in a.c. circuits without much loss of energy. Principle of a choke coil. The working of a choke is based on the fact that when a.c. flows through an inductor, current lags behind the emf by a phase angle of π/2 rad π / 2 r a d. Construction of a choke coil.
