what is the work of a choke in flourescent tube?

Question

in electrical choke is like a rectangular box put in a flourescent engine for reasons i dont know.

Answer 1

sounds like a regulator to me. I guess if it weren't there the tube would explode or something.



Edit: A choke is an inductor designed to have a high reactance to a particular frequency when used in a signal-carrying circuit. They are inductances that isolate AC frequency currents from certain areas of a radio circuit. Chokes depend upon the property of self-inductance for their operation. They are used to block alternating current while passing direct current. Common-mode choke coils are useful in a wide range of prevention of electromagnetic interference (EMI) and radio frequency interference (RFI) from power supply lines and for prevention of malfunctioning of electronic equipment.

Answer 2

I believe the choke is like a secondary switch,i.e., when you turn the power on (e.g. wall switch) it sends the electricity to the choke which in turn fires up the gases in the fluorescent tube ; so no choke (working) --no light.
