Answer to Question 1

A wound rotor is made of coils in which current is supplied through slip rings and brushes to form an electromagnet; a squirrel cage rotor is made of laminated segments and its magnetic field is created by induction.

Answer to Question 2

The exciter can be mounted externally and supply current through slip rings or the exciter can be a rotating armature type exciter that is mounted on the same shaft as the main rotor field and supplies current to the main rotor through rectifying diodes
