NettetE = 4.44fϕmN ⋅ ⋅ ⋅ (6) Equation (6) is known as EMF equation of a transformer. For a given transformer, if we divide the EMF equation by the supply frequency, we get, E f = 4.44ϕmN = Constant. Which means the induced EMF per unit frequency is constant but it is not same on both primary and secondary side of the given transformer.
