Which of the following motor has the poorest speed regulation?

Which of the following motor has the poorest speed regulation? Correct Answer Series motor

If the load is applied to the any DC motor or machine, the speed of the motor decreases automatically. Thus, in order to maintain the constant speed, the difference between no load and full load speed called as speed regulation should be maintained very less. In series motor this difference is almost equal to infinity.
