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.
