In ideal transformer, the following assumptions are made: (i) The winding resistances are negligible. (ii) All the flux produced is confined to the core of the transformer and links fully both the windings. There is no leakage of flux. (iii) Permeability of core is high so that the magnetizing current required to establish flux is … Read more
A transformer may be defined as a static electrical apparatus(electromagnetic device) consist of two or more windings which link with a common magnetic field. Transformers converts electrical energy from higher voltage to lower voltage or vice versa through a medium of electric flux, i.e. it transfers electrical energy from one circuit to another.
