Q) A separately excited de generator is rated for a load voltage of 150 V for a full load current of 20 A at 1500 rpm. With the load disconnected, the output voltage is 160 V. 1. Determine the voltage regulation, the load resistance, the armature resistance, and the developed torque at full load. 2. The speed of the generator is decreased to 1200 rpm, and the load resistance is unchanged. Determine the load current, the load voltage, and the developed power. Solution:

Please solve this problem step by step and illustrate your answer properly. Write your answer in a piece of paper please. Box the final answer.

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?
