Why should we use the igniter in the sodium vapour lamp.
Answer Posted / venkat
as the distance between two electrodes is large, 230v is
not sufficient to produce arc between two electrodes.high
voltage is required to produce arc. Igniter is used to
produce high voltage between two electrodes of the sodium
vapour.
