WebNov 10, 2024 · A choke is basically an inductor. It is used when you want to limit an alternating current without increasing the resistance of the circuit, which could lead to heat dissipation. One example of such a use is the choke used in fluorescent lamps. Applications of choke coil Choke coils are inductive loads and used for, WebThe current passing through a choke coil of selfinductance \( 5 \mathrm{H} \) is decreasing at the rate of \( 2 \mathrm{~A} / \mathrm{s} \). The e.m.f. devel...
[Solved] The inductive reactance of a coil at 100 Hz is 20
WebThe inductance of a choke-coil is 0.2 henry and its resistance is 0.50Ω. If a current of 2.0 ampere (rms value) and frequency 50Hz is passed through it, what will be the potential difference across its ends? A 145.6V B 125.6V C 135.6V D 185.6V Medium Solution Verified by Toppr Correct option is B) We Know, WebThe inductor is also called a choke, reactor, or coil. The inductor either acquires charge or loses its charge on every use, for equalizing the current flowing through it. The inductor voltage can measure the amount of voltage generated for a particular rate of change of current. Reactor Read More: AC Voltage applied to an inductor how to rollover 401k to fidelity 401k

WebIn a choke coil, the reactance X L and resistance R are such that :- A X L=R B X L>>>R C X L<< WebIn do machines, 1. The reactance voltage is proportional to armature current 2. The reactance voltage is proportional to core length 3. The reactance voltage is due to self flux of the coil undergoing commutation 4. Armature cross flux is neutralized by interpolar flux 5. Interpolar mmf is more than armature mmf in the interpolar zone From ... WebThe reactance of a choke coi is given by X,=2e fE Forde, f=0s0Xp=0 Thus a choke coil does not, oppose current in a dic. circuit. So it cannot be used to control d.c, Problem 1. Answer the following questions : (a) For circuits used for transporting electric power, 4 low power factor implies large power loss in transmission. northern ireland car rentals
