i have got some information about transformers used in mobile chargers from my frnds and that is most transformers are the old style, which are essentially a short circuit over...

i know that even though there is no load on secondary winding of the transformer there will be current passing through the primary winding and hence there may be losses...

am 2nd yr student in electrical engineering i have read in a news paper that there will be 30% losses when we connect a charger to power supply even though...

hey can any one help me.......... can any one give me an interesting topic for my 3rd year mini project.......
