Answer / raghavendra

In conventional fluorescent lamps (4 feet long) and in CFL's the used component is a choke. It is a leak transformer(made of bulk coil winding ) produces a inductive kick in the form of high voltage nearly 1000 volts so that the electrical discharge could be struck along the tube.so in fluorescent lamp choke acts as to initiate the electrical discharge process

1.what is use of isolation transformer. 2.Differance between KWH,KVAH,KVARH,KVA. 3.Main use of the CT and PT.

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??
