why copper is a bad conducter at low temperature?
i measured a 3-ph capacitor with a multimeter which is not connected to supply... but i could get the phase to phase voltage... how tis is possible..????
I just want to convert the voltage into current i.e. suppose I have 750V & 1A AC power then I want to convert it into 12V & 62A DC power only difficulty is that I don't want to use the tranceformer. Simply to say, I want to make the step-down without using tranceformer. Please, give me some ideas. And also I want the relation between Magnetic Induction & Weight of the body can be levitated.
