Write the Emf equation of transformer. State the meaning of each term in it. 

1 Answer

Answer :

EMF equation of Transformer:-

E1 = 4.44 f ØmN1 OR E1 = 4.44 f BmAN1

E2 = 4.44 f ØmN2 OR E2 = 4.44 f Bm AN2

Let, E1 = Primary emf

E2 = Secondary emf

N1= Number of turns in the primary

N2= Number of turns in the Secondary

Øm= Maximum flux in core (wb)

Bm= Flux density (wb/m2 /Tesla)

A= Area of cross section of core m2

F = Frequency
