The figures below show the equivalent circuit of a separately excited DC generator and the approximate relationship between the flux of main field and exciting current. The field current I can be regulated by the variable resistor Ry, and the battery voltage supplying power to the exciter is 12V. The armature resistance Ro is 20, and the load is 182. For the DC generator, we aim to keep the voltage across the load (RL) constant in different speed range conditions. In the beginning, the flux is 0.12 Wb, the DC generator speed is 1000 rpm, and the generated voltage E。 is 100 V. Calculate: (1) The current flowing through the load.
