Answer Posted / karthik
The starter is basically a time delay switch. Its job is to
let the current flow through to the electrodes at each end
of the tube, causing the filaments to heat up and create a
cloud of electrons inside the tube. The starter then opens
after a second or two. The voltage across the tube allows a
stream of electrons to flow across the tube and ionize the
mercury vapor.
Without the starter, a steady stream of electrons is never
created between the two filaments, and the lamp flickers.

WE know that for Inductor X=2pifL,In DC f=0,then X=0 so,V=IX=0;But In the DC excitation of rotor of AC generator,DC motor field coil which coils are inductor so why does not applying DC voltage short the rotor coil of AC generator and field coil of motor?If it would then DC source might be damaged but it is not happened. Why does the strand conductor of Electrical power transmission line make twist?
