This Answer Is B
The full-load copper loss of a transformer is 1600 W. This means that at full-load, the transformer’s copper loss is 1600 W. At half-load, it is expected that the copper loss will be lower than at full-load.
This is due to the transformer’s efficiency being higher when running at a lower load. Therefore, it is important to consider the copper loss when selecting a transformer for a given application.
