This page shows the derivation of emf equation of transformer. It also includes transformation ratios. There are three types of transformation. A transformer is a device which uses the phenomenon of mutual induction to change the values of alternating with both primary and secondary coils and induces in them e.m.f.'s of E1 and. E2 respectively by e.m.f. equation of a transformer. In a transformer, source of alternating current is applied to the primary winding. The magnetizing current produces alternation flux which gets linked with.

The derivation of the EMF Equation of the transformer is shown here. The rate of change of flux with respect to time is derived mathematically. EMF EQUATION OF TRANSFORMER. Let,. N1=Number of turns in primary. N2= Number of turns in secondary. Φm=Maximum flux in core in webers. = Bm*A. Let N1 = No. of turns in primary. N2 = No. of turns in secondary. Øm = Maximum flux in core in webers = Bm x A. f = Frequency of a.c. input in Hz. The flux.
EMF Equation of transformer can be established in a very easy way. Actually in electrical power transformer , one alternating electrical source is applied to the primary winding and due to this, magnetizing current flowing through the primary winding which produces alternating flux in the core of transformer. This above stated ratio is also known as voltage ratio of transformer if it is expressed as ratio of the primary and secondary voltages of transformer. Moreover, we already know that from the power equation of the transformer , i. When a source of alternating current AC is applied to the primary winding of the transformer which is known as magnetizing current , it produces alternating flux in the core of a transformer. In this way, we can easily derive the emf equation of transformer.
