tubelight works on the principle of electric discharge.
starter act as a switch and choke acts as an inductor. when
tubelight is switched on the electricity flows through
starter which is actually a capacitor. sooner the dielectric
strength decreases and it gets shorted hence switching of
the supply through inductor. during this time the choke
stores energy which is appeared across the electrodes of the
tubelight and hence helps in ionsation of gas and electric
discharge. starter is connected in parallel to tubelight and
choke is in series

We know that primary transmission is done to reduce current so that i^2*r loss could be minimised but according to ohm's law v is directly proportional to i,which indirectly means higher potential difference means larger current?so how the current is minimised in high power transmission line??
