what is the use of choke on tube light fitting
Answer Posted / rathnam
the property of the inductor is to oppose the rate of
change of current through it suddenly. At the time of
starting it requires high voltage to ionise the gas (
through creating potential difference between the
electrodes) in the tube so choke creates required potential.
The starter is same as that of a capacitor, to improve the
power factor the total system(connection of R and L) it is
required.
