1. An electro-mechanical energy conversion device is one which converts mechanical from electrical and electrical from mechanical. Explain.

2. Explain the coupling field used between the mechanical and electrical systems in energy conversion devices is electrical field/magnetic field.

3.Why is energy storing capacity of magnetic field is about 25,000 times greater than that of electric field.

4. 1/2 mv2 is the type of formula for energy stored in the mechanical system of linear motion. Explain.

5. The developed electromagnetic force and/or torque in electromechanical energy conversion system, acts in such a direction that tends to ___________

a) increase the stored energy at constant mmf

b) decrease the stored energy at constant mmf

c) decrease the co-energy at constant mmf

d) increase the stored energy at constant flux
