For a four pole, 16 slot armature with two coil-side/slot having wave connected progressive winding has single turn coils has simplex winding. The number of current paths is?

The amount of inrush current in the primary of a transformer is limited by the........, A- amount of applied voltage, B- resistance of the wire in the primary winding, C- flux change of the magnetic field in the core, D - all of the above What precaution must be observed when working whit current transformers? A- never have a load on the secondary, B- always ha a load on the secondary, C- de-energize the primary whenever there is a load on the secondary, D - none The fact that the movable coil of a constant-current transformer moves further away from the stationary coil with a increase in load current is based on which fundamental priciple of magnetism? A- like magnetic poles attract, B- like magnetic poles repel, C- the amount of current flowing through a coil inverdely proportional to its flux density. D- none

Assume a single phase transformer with primary and secondary winding. Explain what would happen if a third winding with a constant DC voltage would be added to the same magnetic circuit. ...
