What is one way of limiting current in-rush?
What will be an ideal response?
One method of limiting this current is to connect resistors in series with the armature. When the armature begins to turn, counter-EMF is developed in the armature. As counter-EMF increases, resistance can be shunted out of the armature circuit, permitting the armature to turn at a higher speed. When armature speed increases, counter-EMF also increases. Resistance can be shunted out of the circuit in steps until the armature is connected directly to the power line.
