Why choke coil is used in tube light?
To limit the current through the lamp when the gas ionises and conducts.

How do you calculate the volume occupied by the tube side of a shell and tube heat exchanger?
Measure the outer diameter of the tube and its' length. Calculate each tube volume and multiply by number of tubes. For those who want to calculate the inside liquid capacity of the shell side, it is advise to include the baffle volume with the tube bundle volume.
How choke coil limit current to the fluorescent tube?
A choke coil, also known as a ballast, limits the current to a fluorescent tube by providing a high impedance to the flow of current. This high impedance restricts the current flowing through the tube, allowing it to operate within its required current range. The choke coil also helps regulate the starting voltage and stabilize the operation of the tube.

How can you calculate the current in 40 X 40W tube lights in 230V?
power is = V2/R so 40x40= (230)2/R R= 33.25 now V= IR where I is current 230= IXR I= 230/33.25 = 6.9 amp
How tube light start by using starter?
A starter initially provides a path to complete the circuit. The tube light starts when the current flows through the ionized gas in the main tube. woodenboatusa.com
How does electron allow a fluroscent tube to glow?
The electrons in the mercury arc current in the tube causes the mercury vapor to emit ultraviolet light. The inside surface of the tube is coated with a phosphor that glows with visible light when hit by ultraviolet light.

What is the difference between the normal light globe and a fluorescent tube?
"Normal" light globes use a glowing filament, heated by the current. Flourescent tubes ignite a gas within a tube, using an arc.
