A separately-excited shunt DC generator has an armature resistance of 0.025 ohms, delivering 40 kW with a generated armature emf being 255 V. Find the terminal voltage and the corresponding armature current. If the terminal voltage is maintained at 253 V and the generated armature voltage is 257 V, what would be the load power?
