Question

In a transformer, in practice the output power is always less than the input because of the following power loss:

• A. Loss due to the heating
• B. Loss due to eddy currents
• C. Hystersis loss
• D. All the above

Answer 1

The correct option is D All the above

D

The output power in a transformer is always less than the input power because of the different losses in a transformer. The losses may be Iron loss or core loss, hysteresis loss, eddy current loss, copper loss etc.
