SECTION A

Q1:- Attempt any two of the following :

1. Define energy and co-energy. What is significance of co-energy? Show that the field energy in a linear magnetic system is given by W_f = 1/2Li² = 1/2 Ψi = (1/2L)Ψ².
2. Derive an expression for the torque in the doubly excited system having salient pole type of stator as well as well as rotor. State the assumption made.
3. For an electromagnetic system, show that the mechanical work done is equal to the area enclosed between two magnetization curve at open and closed position of the armature and  Ψ-I locus during the armature movement.
