In AC. circuits, laminated iron is invariably used in order to__________?
Correct answer: A. reduce eddy current loss
- A. reduce eddy current loss
- B. increase heat radiation
- C. make assembly cheap and easier
- D. reduce circuit permeability
Explanation
Laminating an iron core breaks up the paths available for circulating eddy currents, greatly reducing eddy-current loss. The laminations are insulated from one another to increase this effect.
