what is the function of starter & choke in the tube light
set & how choke give 1000 volts while switching on.
Answer Posted / raj
the starter function is used simply step up the voltage
level at the time of starting by using resistor and
inductor phenomenon and at the same time the starter
maintain the voltage for excitation of gases molecules
after some time by comparable no energy drawn from source

In Dyn11 power transformer if any one of the 3 phases connected to earth in star connected side then please explain effect of the current flow in delta connected side of transformer.(In this case if one phase is shorted to ground in star connected side then we observe the current flow in two phases only not three phases in delta connected primary side. Please explain why it is so?)
