WebNov 25, 2024 · The emf equation of a transformer is derived by considering a single-phase transformer. When a single-phase AC supply is given to a transformer, the emf gets induced in the secondary winding … WebJan 6, 2024 · The derivation of the EMF Equation of the transformer is shown below. Let. Φm= Maximum value of flux in the core, Wb. f = Frequency of a.c input supply in Hz. N1 = number of turns in the primary winding. N2 = number of turns in the secondary winding. Φ = the flux per turn in Weber. Since flux increases from its Zero value to the maximum value ...
