high reluctance
low reactance
high resistance
low resistance
Answer is Wrong!
Answer is Right!
The correct answer is: low reluctance.
Reluctance is the opposition to the flow of magnetic flux
in a magnetic circuit. It is analogous to resistance in an electric circuit. The lower the reluctance, the easier it is for magnetic flux to flow.The path of the magnetic flux in a transformer should have low reluctance so that the magnetic flux can flow easily and produce a strong magnetic field. This is necessary for the transformer to operate efficiently.
The other options are incorrect.
- High reactance would cause the magnetic flux to flow more slowly, which would reduce the efficiency of the transformer.
- High resistance would cause the magnetic flux to be dissipated as heat, which would also reduce the efficiency of the transformer.
- Low resistance would not affect the flow of magnetic flux, but it would not be necessary for the transformer to operate efficiently.
