Expert Answer:

A starter is actually a capacitor connected in parallel with a fluorescent lamp.
To strike a f.lamp a sudden spark of current discharge is required in the tube.the starter supplies this initial spark.
when a tube light arrangement is connected to the supply,the starter charges(charging is as in a capacitor).a starter current flows during this session.
on reaching the striking voltage(the voltage just needed to flash the light for the first time) the starter discharges and a sudden current flows in the tube ionising the gas and giving it the glow.
after this starter current becomes nil.
