Which of the following are true about Transformers.
1) Function of transformer is to convert stored high powerelectrical energy into low power electrical energy
2) Voltage across secondary step-up transformer is greater thanthat across the primary
3) They only operate on dc current
4) voltage across the secondary of step-up transformer will besmaller than that across the primary
5)current through primary step down will be smaller than currentthrough the secondary
6) function of transformer is to convert stored low powerelectrical energy into high power electrical energy
7) Ignoring dissipative losses, the power through the secondary ofa step-down transformer will be less than the power through theprimary.
