It is important to note that that transformer input and output are isolated from one another, in the sense that an electrical charge cannot move from input to output. The energy is transferred via the magnetic field. The alternating current in the input causes a magnetic field; this magnetic field causes an alternating current in the output.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
