Hm... Thanks a lot guys. :) How do I close this thread though? My queries have pretty much been answered. Edit: Ok wait the vibration thing is kind of confusing though. Which is it? :O I did check the hum sound out, it kind of sounds like the hum along the power lines.

Hmm... I'll take that into account. Thanks a lot for your help. On another note, what causes the vibrations through the iron core when the current flows through??

Uhh so basically the adapter is bought to step the voltage down from 240V (from wall plug) to a safe experimental 12V 0.7A AC current, and then I use my model like the one in the link below to step it down further to 6.0v~. Basically I am required to demonstrate how a AC transformer works...

Hi guys, I am rather new here and would like to pose a question about transformers. As physics assignment I am supposed to make a model of an AC transformer, for which I grabbed an AC/AC step down adapter (something like these here...
