Its a step down transformer to begin with!

And if u consider it to be an ideal transfomer then u have a nice transfomer equation.. do you know what that is?

anonymous · Answer

No, do you?

lol :D..
If you dunno the transformer equation.. I first advice you to go through your notes or texts and understand how a transformer works!

yeah i might have missed that on my notes lol
