small air gap
large leakage flux
laminated silicon steel core
fewer rotating parts
Answer is Wrong!
Answer is Right!
The correct answer is: C. laminated silicon steel core.
The magnetizing current of a transformer is the current that flows through the primary winding of the transformer to create the magnetic field that induces a voltage in the secondary winding. The magnetizing current is usually small because the laminated silicon steel core has a high permeability, which means that it is easily magnetized. The high permeability of the core reduces the amount of current required to create the magnetic field.
The other options are incorrect because:
- A. A small air gap increases the magnetizing current.
- B. A large leakage flux increases the magnetizing current.
- D. Fewer rotating parts does not affect the magnetizing current.
