Choke (ballast) produces around 11000v at starting time of
flourecent tube to move the electrons from flements of two
sides for closing of circuit. after that tube will glow on
around half of the supply voltage.

Answer / priya

choke is a circuit element used to limit the flow of
alternating current without affecting the flow of direct current

Answer / rishabh dubey

Choke(Ballast)provide a High voltage which is required for
ionisation of particles og tube light(approx.)-600 volt and
after this limit the current

Answer / ramanharikrishnan

Choke (ballast) produces around 11000v at starting time of
flourecent tube to move the electrons from flements of two
sides for closing of circuit. after that tube is blowing
with 230 V.

Answer / vijayalakshmi

choke is coil which ignit the arc between the two electrode

Answer / rajeshwar

choke is highly inductive , so it opposes any sudden change
of voltage .
At start it stores electrical voltage and passes it with
high amplitude within sec(1000-1200V) for ionisation of
gases in tube bar .

How much allowable difference current between on three phases Dear sir, We have a 1870 KW HT motor, 11 Kv supply,FLA-120A,2870 rpm,2-pole squirrel cage induction Motor.And stator is connected in star connection with Liquid resistance stater to limit the starting current.It has coupled with Centrifugal air compressor.My question is it is loading 73% of FLA taking R-phase 86.7 A, Y-phase-85.4A,B-phase- 78.3A.why the B phase current is that much of difference.Is it allowable, or any one tell me how much allowable current.If any method to calculate.
