SUMMARY

The discussion addresses the operation of tube lights, specifically focusing on the initial flickering when switched on and the roles of starters and capacitors. It is established that the flickering occurs due to the starter allowing current to flow initially, which then opens its contacts, creating a high voltage kick from the inductor or ballast that ignites the tube light. Additionally, starters and capacitors are distinct components; the capacitor is not solely for power factor improvement but plays a crucial role in stabilizing the electrical circuit.

Homework Statement


Q1)why will there be initial flickering when we siwtch on tube light
Q2)is starter and capacitor both are same ?(OR)are both of them are enclosed in a single package?

Q3)what is the function of capacitor, is it for power factor improvement?



Homework Equations





The Attempt at a Solution



As far as i know,when we sitch on supply, current passes through starter and after some time, contacts of starter gets opened, causing high voltage kick by inductor or ballast making the tube light glow.But i still could not answer the above queries.
