Derivation of emf equation of transformer
WebFeb 20, 2024 · We solve Equation 23.10.3 for Ns, the number of loops in the secondary, and enter the known values. This gives Ns = NpVs Vp = (50)100, 000V 120V = 4.17 × 104. Discussion for (a): A large number of loops in the secondary (compared with the primary) is required to produce such a large voltage.
