How transformers work?

  1. Nov 11, 2006 #1
    Ohm's law states that at constant temperature the flow of electricity through a conductor is proportion to the potential difference accross the conductor. But It always appeared to me that transformers are indifferent to this law. Here, how it is.
    A step up transformer induce larger voltage from the primary coil to secondary coil. But the electron flow falls. Primary coil has relatively lower voltage but higher flow of electrons. The secondary coil has vice versa. Does it violate Ohm's law (V=IR)?
    Please help.

    Transformers don't violate Ohm's law. Google on transformer and see why they act the way they do, and pay attention to the way the number of turns in the windings affect the voltage and current flow.
