The path of magnetic flux in a transformer should have high resistance low reluctance high reluctance low resistance Which of the following does not change in a transformer? a. Current b. Frequency c. Impedance d. Voltage Which winding in the transformer has more number of turns? Low-voltage winding Secondary winding High-voltage winding Primary winding A transformer cannot raise or lower the voltage of a DC supply because a DC circuit has more losses Faraday's law of electromagnetic induction is not valid since the rate of change of flux is zero there is no need to change the DC voltage of the impractical size of the transformer Ideal transformers do not exist in real life.
