Answer Posted / dileep
At the time of starting a tube choke gives rise to high
voltage by di/dt nearly 1000 volts by starter ON-OFF
function rate of change of voltage becomes high due to
inductance of choke. This high voltage starts ionization of
gas in the tube. Once gas gets ionised and starts
conducting then starter gets out of circuit and circuit is
completed only through choke which now share voltage(limit
voltage) for tube because after esabilishing ionization now
to maintain it only nearly half of the voltage is required.
