Explain choke coil
WebThe choke has two main functions. It (in conjunction with the starter if it has one) causes. the tube to ignite by using the back emf to create a plasma in the tube and it controls the. current through the tube when it is ignited. fIn a gas discharge, such as a fluorescent lamp, current causes resistance to decrease. WebThe choke coil is used to provide less reactance at the usual power frequency and also provides high reactance at transient frequency. Therefore the choke coil doesn’t permit the transients to go into the …

Webaxis of a coil. Magnetic Fields Around Coils. When the conductor is bent into a loop or coil however, the direction of the magnetic fields inside the coil coincide, concentrating the magnetic flux within the coil as shown in Fig 3.1.4. Fig. 3.1.2 Right Hand Grip Rule. Fig. 3.1.4 Magnetic Field Around Looped Conductors. WebThe choke coil works because it can act as an inductor. When the current pass through will change as AC currents creates a magnetic field in the coil that works against that current. This is known as inductance and blocks most of the AC current from passing through. This result to the currents that do not change such as DC currents can continue ...
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.

Impedance of choke increases with increase in frequency. Choke or coil is also …
WebLenz’s law, in electromagnetism, statement that an induced electric current flows in a direction such that the current opposes the change that induced it. This law was deduced in 1834 by the Russian physicist Heinrich … WebSelf-inductance is the property of the current-carrying coil that resists or opposes the change of current flowing through it. This occurs mainly due to the self-induced emf produced in the coil itself. In simple terms, we can also say that self-inductance is a phenomenon where there is the induction of a voltage in a current-carrying wire.
WebA given choke coil is usually represented by a pure inductance (L) in series with equivalent resistance (r). This equivalent resistance takes into effect the iron losses in the core of the choke coil and the inherent resistance of …
