Problems

1. A solenoid transformer has 3V and .5 A on its primary winding. The leakage flux of this transformer is 2Wb. Find the amount of flux created and by primary winding, the flux created by the secondary winding, and the efficiency of the transformer.

2. An non-ideal 2-phase transformer core has Rc1= 2 Ohms and Lw1= 5 micro Henrys. The average flux created when the transformer is connected to an open circuit is 5Wb. Find Rc2 and Lw2.

3. The flux created by a transformer’s primary winding is 3Wb and the flux from the secondary is 1WB. Find the leakage flux.

4. Find the amount of energy lost in a magnet by using Green’s theorem to approximate the area of its characteristic BH curve shown.

5. Derive the power equation for an ideal three phase transformer. Interms of
