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 + Iw + Iμ.ok I1 = KI2 + Iμ. I1 = KI2. I1 = KI2 + Iw. I1 = KI2 + Iw + Iμ.ok I1 = KI2 + Iμ. I1 = KI2. I1 = KI2 + Iw. ANSWER DOWNLOAD EXAMIANS APP
Electrical Machines A compound dc generator is delivering full load current at a terminal voltage of 230 V. Its series-field winding gets short circuited. If its terminal voltage 1. becomes more than 230 V, it is overcompounded generator 2. becomes more than 230 V, it is differentially compounded generator 3. becomes less than 230 V, it is overcompounded generator 4. becomes less than 230 V, it is differentially compounded generator 5. becomes less than 230 V, it is level compounded generator From these, the correct answer is 1, 4, 5 2, 3, 5 2,3 1, 4 1, 4, 5 2, 3, 5 2,3 1, 4 ANSWER DOWNLOAD EXAMIANS APP
