    how e1 and e2 lag behind flux by 90
    how applied voltage and induced emf equal in secondary of transformer and differ in primary winding
    where single phase transformers generally used compared to 3phase transformer
    how primary winding current sets fluxlinkage and induces emf in secondary first intead of primary why
    where i can get free objective question material on electrical subject on internet

    three phase transformers can be made by two ways.. 1st we can use a bank of three single phase transformer or we may use a single 3 phase transformer...a bank of transformers are easy to transport.but the best thing is that if any one of the transformer i three of them is get damaged,then it can be easily replaced and THE CONTINUITY OF POWER CAN BE MAINTAINED,AND THATS WHAT WE NEED...
    BUT,the same is not possible in the case of a single 3 phase transformer..its heavy,not easy to transport..and if thy get damged then whole system has to be removed which can make a difficult circumstances to the operator......

    i hope it is sufficient to understand this answer....
