Ask qu1. If the resistor Radj is adjusted to 175O what is the rotational speed of the motor at no-load conditions?

2. Assuming no armature reaction, what is the speed of the motor at full load? What is the speed regulation of the motor?

3. If the motor is operating at full load and if its variable resistance Radj is increased to 250 O, what is the new speed of the motor? Compare the full-load speed of the motor with Radj = 175O to the full-load speed with Radj = 250Oestion #Minimum 100 words accepted#
