Using the principle of electromagnetic induction, A transformer changes an alternating voltage (potential difference) from one value to another whether it is smaller or greater.
To identify a primary and secondary coil of a transformer first of all you have to understand what a transformer is
A transformer consists of a soft iron coil with two coils wound around it which are not connected to one another.
The term Primary and Secondary coil is given to a transformer to understand its working in a simpler way which I described below in short.
The coil to which the alternating voltage is supplied is called the primary coil or primary winding. The alternating potential difference of this coil results in an alternating current in the primary coil and produces a changing magnetic field around it, due to this changing magnetic field or flux an alternating current is induced in the Secondary coil and an alternating voltage is induced in secondary coil.
