Extracted text: A long shunt de generator supplies 8 kW at voltage of 250 V. The armature resistance, shunt field resistance and series field resistance are 0.45 2, 125 N and 0.05 N respectively. The machine works with the mechanical losses of 0.4 kW and efficiency of 80%. Draw the circuit with indication all values and find: i) The armature current ii) The copper losses iii) The develop power iv) The generating EMF v) The core losses
