In a well-designed transformer with an iron core, the secondary coil has twice as many turns as the primary coil. Which one of the follo statements concerning this transformer is true? OA This is a step-down transformer because the current in the secondary coil is less than that in the primary coil. OB. The effect of the iron core is to reduce the magnetic field passing through the coils. C The induced emf generated in the secondary coil is twice as large as that generated in the primary coil. 9:44 PM O D. The flux that passes through each turn of the primary coll is twice the flux that passes through the secondary coll.
