Wht Transofomer Is Called A Machine?

  1. Jan 4, 2006 #1
    Hi Guys!

    well ! i have one question to you?


    Why transformer is called a machine. It has got no rotor in it. Then what is the reason that we put transformer in the category of machines.

    Thanks in advance!

    Technicaly anything that converts energy from one form to another is a machine. It doesn't have to be electrical to mechanical. Resistance coils are a machine also in the strictest sense since they convert electricity to heat. A transformer converts one "flavor" of electricity to another.
    Or so goes my humble opineo:)
