Electrical Machines If a transformer has turns ratio K, the primary and secondary current are I1 and I2 respectively and magnetizing current and core loss component of no load current Iμ and Iw respectively, then I1 = KI2. I1 = KI2 + Iμ. I1 = KI2 + Iw + Iμ.ok I1 = KI2 + Iw. I1 = KI2. I1 = KI2 + Iμ. I1 = KI2 + Iw + Iμ.ok I1 = KI2 + Iw. ANSWER DOWNLOAD EXAMIANS APP
