Mechanical strength
Low hysteresis loss
High thermal conductivity
High permeability
Answer is Wrong!
Answer is Right!
The correct answer is C. High thermal conductivity.
The other options are desirable in the material for transformer core.
- Mechanical strength is important to ensure that the core does not deform under the weight of the transformer and the magnetic field.
- Low hysteresis loss is important to reduce energy losses in the core.
- High permeability is important to allow the core to produce a strong magnetic field.
High thermal conductivity is not necessarily desirable in the material for transformer core. This is because it can lead to the core overheating, which can damage the transformer. In some cases, it may be desirable to use a material with low thermal conductivity to help dissipate heat away from the core.
