What is choke coil answer?
A choke coil is an inductance coil of very small resistance used for controlling current in an a.c. circuit. On the other hand there is no dissipation of power when a current flows through a pure inductor.
What is the meaning of choke coil?
Definitions of choke coil. a coil of low resistance and high inductance used in electrical circuits to pass direct current and attenuate alternating current. synonyms: choke, choking coil. type of: coil. reactor consisting of a spiral of insulated wire that introduces inductance into a circuit.
What is choke coil Byjus?
A choke is a wound coil generally used for smoothing or filtering the outputs from rectifying circuits. Impedance of chokeincreases with increase in frequency. Choke or coil is also used for RF filtering.
What is choke coil Quora?
Choke coil is a low resistance inductor coil which is use to limit the current in the ac circuit without having much power loss . It is also use to block high frequency. 3.7K views. · Rajib Ghosal.
What is the power factor of a choke coil?
zero
, the power factor of a good choke coil is virtually zero i.e, cosϕ=0. Also, choke coils are used in electrical circuits to limit current.
What is the difference between a choke and an inductor?
Because choke is basically used to stop the frequency, while Inductor has various uses including this one. Choke is just a type of Inductor. The basic difference between choke & any other type of Inductor is, Choke has a ferro-magnetic material as its core which increases its inductance.
Where do we use choke coil?
Choke coil is used in fluorescent lamps or tubes, initially it provides a very high voltage and once the gas in the tube is ionized, choke provides a low voltage. Usually it is used to allow DC and blocks AC to pass through the circuit.
Can we use choke coil in DC circuit?
The choke coil can be used only in ac circuits, not in dc circuits, because for dc(ω=0) the inductive reactance XL=ωL of the coil is zero, only the resistance of the coil remains effective which too is almost zero.
