Q:How tube light circuit is connected and how it works?

A:A choke is a connected in one end of the tube light and a starter is in series with the circuit. When supply is provided the starter will intrupt the supply intermittant cycle of AC. Due to the sudden change of supply the chock will generate around 1000volts . This volt will capable of to break the electrons inside the tube to make elctrone flow. once the current passess through the tube the starter circuit will be out of part. now there is no change of supply causes choke voltage normalised and act as minimise the current.
